Reaction Steps
A 40 mL tube is charged with 2-[(2-cyclobutoxy-3-methyl-benzoyl)-amino]-indan-2-carboxylic acid (323 mg, 0.884 mmol) and dry DCM (7 mL). A stirring bar is added and stirring is initiated. 5-Amino-1H-tetrazole (113 mg, 1.33 mmol) is added. To the resultant suspension, N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (170 mg, 0.88 mmol) and 4-dimethylaminopyridine (108 mg, 0.88 mmol) is added. After 11½ days, tlc analysis (silica, 10% MeOH in DCM) indicates that the starting acid had been consumed. The reaction mixture is diluted with EtOAc (50 mL), transferred to an Erlenmeyer flask containing saturated aqueous ammonium chloride (50 mL). This mixture is allowed to stir. After 16 h of stirring, this mixture contained a white solid that is collected by suction filtration and washed with water (2×25 mL). Air drying gives 0.26 g of white powder.
