General Information All starting materials and reagents were commercially available and used directly without further purification. All carboxamides were synthesized by the reactions between the corresponding acyl chlorides or acids and 8-aminoquinolines according to the literature procedures. 1 All known products gave satisfactory analytical data by MR spectra, corresponding to the reported literature values. In addition, unknown compounds were confirmed by HRMS. Melting points were determined using X-4 micro melting point apparatus and are uncorrected. MR spectra were recorded at room temperature on a Bruker Avance-300 or Bruker Avance-500 at 300 MHz or 500 MHz with tetramethylsilane (TMS) as an internal standard. Chemical shifts are given in δ relative to TMS, the coupling constants J are given in Hz. High-resolution mass spectra (HRMS) were recorded on Agilent 6200 LC/MS TF using APCI or ESI in positive mode. General Procedures General Procedure for Copper-Catalyzed C H Acyloxylation To a 10 ml reaction tube was added amide 1a (0.2 mmol), acid (0.3 mmol), CuBr (5.7 mg, 20 mol %), Ag 2 C 3 (110.3 mg, 2 equiv), and toluene/dmf (1.5 ml/0.5 ml) in air. The mixture was stirred at 130 for 15 h. The reaction mixture was then cooled to room temperature, diluted with ethyl acetate and quenched with saturated sodium chloride. The aqueous phase was extracted with ethyl acetate (3 10 ml). The organic layer was dried over a 2 S 4. After concentration, the resulting residue was purified by flash chromatography to afford the product. Copper-Catalyzed C H Acyloxylation of 1a with benzoic acid (2 mmol scale) To a 50 ml reaction tube was added amide 1a (524 mg, 2 mmol), benzoic acid 2a (366 mg, 3 mmol), CuBr (57 mg, 20 mol %), Ag 2 C 3 (1103 mg, 2 equiv), and toluene/dmf (15 ml/5 ml) in air. The mixture was stirred at 130 for 15 h. The reaction mixture was then cooled to room temperature, diluted with ethyl acetate and quenched with saturated sodium chloride. The aqueous phase was extracted with ethyl acetate (3 40 ml). The organic layer was dried over a 2 S 4. After concentration, the resulting residue was purified by flash chromatography on silica gel (eluent: petroleum ether/ethyl acetate = 12/1) to afford the desired alkylated product 3aa (581 mg, 76%) as a white solid. 1 (a) Grigorjeva, L.; Daugulis,. rg.

X-ray crystal structure of the compound 5ba Figure S1. RTEP view of 5ba. [2] The hydrolyzation of 5ba Scheme S1 The compound 5ba was prepared according to general procedure (the reaction time was extended to 30 h). To a 10 ml reaction tube was added amide 5ba (0.2 mmol) and aqueous ah (2 ml). The mixture was stirred at 110 for 24 h in air, and reflux. The reaction mixture was then cooled to room temperature and added aqueous HCl, adjusted the ph of the solution to 6~7. The aqueous phase was extracted with ethyl acetate (3 10 ml) and the organic layer was dried over a 2 S 4. After concentration, the resulting residue was purified by flash chromatography to afford the product 7a. [2] CCDC-1526975 (for 5ba) contains the supplementary crystallographic data for this paper.
