Procedure

This compound was obtained following Method B starting from 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.0459 g, 0.195 mmol), 2,5-dimethyl-1,3-oxazole-4-carbonyl chloride (0.032 g; 0.195 mmol), and triethylamine (0.0683 mL; 0.486 mmol) in dichloromethane (3 mL). Flash chromatography on silica gel eluting with 2 to 20% of ethyl acetate in dichloromethane gave 0.0414 g (67%) of N-(2-(5-Chloro-1H-indol-3-yl)ethyl)-2,5-dimethyloxazole-4-carboxamide as a solid.
