Trifluoroacetic acid → N-(5-chloropyridin-2-yl)-5-iodo-2-[(4-piperidinylcarbonyl)amino]benzamide trifluoroacetate

Participants

Reaction Steps

To a stirring solution of 2-[(1-tert-butoxycarbonylpiperidin-4-ylcarbonyl)amino]-N-(5-chloropyridin-2-yl)-5-iodobenzamide (2.0 g, 3.45 mmol) in dichloromethane (65 mL) and anisole (2 mL, 18 mmol) was added trifluoroacetic acid (6.7 mL, 87 mmol). The reaction solution was stirred at room temperature for 4 h, concentrated in vacuo, treated with diethyl ether and concentrated (3×), treated with diethyl ether, sonicated, and filtered to give 1.86 g (90%) of a gray solid.
