Procedure

To a solution of 1-(1-(4-chlorophenyl)ethyl)-2-methyl-1H-indole-3-carboxylic acid (200 mg, 0.64 mmol) in anhydrous DCM (5 mL) was added HOBt (130 mg, 0.96 mmol), EDCI (184 mg, 0.96 mmol) and Et3N (194 mg, 1.92 mmol) at room temperature under N2. The reaction was stirred for 30 min and then 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (107 mg, 0.7 mmol) was added. The reaction was stirred at room temperature overnight. The mixture was diluted with water and adjusted to pH 7 and extracted with DCM. The crude product was purified by silica gel chromatography (Eluent: DCM:MeOH=30:1) to afford the title compound a yellow solid.
