Reaction Steps

0.015 mL of N,N-dimethylformamide was added to a mixed solution of 2.0 mL of methylene chloride and 0.024 mL of oxalyl chloride containing 47 mg of 6-(1H-pyrrol-1-yl)pyridine-3-carboxylic acid and stirred at room temperature for 30 minutes. 74 mg of tert-butyl 2-amino-4-phenethylbenzoate and 0.090 mL of triethylamine were added to the reaction mixture at room temperature sequentially and stirred at the same temperature for 1 hour and 40 minutes. 1.0 mol/L hydrochloric acid and ethyl acetate were added to the reaction mixture. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium chloride aqueous solution, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [PSQ100B (spherical) manufactured by Fuji Silysia Chemical Ltd., eluent; chloroform] to obtain 62 mg of tert-butyl 4-phenethyl-2-(6-(1H-pyrrol-1-yl)pyridine-3-carboxamido)benzoate as white solid.
