実験手順

A solution of 4-amino-5-chloro-2-methoxy-N-(3-methoxy-piperidin-4-yl)-benzamide (1 g, 3.2 mmol), and 241 μL of acrylic acid in 50 ml dichloromethane was stirred under nitrogen for 6 hr then concentrated in vacuo. The residue was slurried with hot ethyl acetate and filtered at room temperature to yield 1.15 g of product as a white solid.
