Procedure
A stirred solution of biphenyl-2-ylcarbamic acid piperidin-4-yl ester (50.0 g, 168.7 mmol) (see, e.g., U.S. Patent Publication No. 2006/0035931 A1, published Feb. 16, 2006) and acrylic acid (15.1 mL, 219.3 mmol) in DCM (500 mL) was heated at 50° C. overnight. The reaction mixture was concentrated under reduced pressure and the residue was dissolved in MeOH (600 mL). The resulting solution was heated at 75° C. for 2 h and then allowed to stand at room temperature for about 48 h. The resulting solid was collected by filtration, washed with MeOH, and dried to give the title compound (61.5 g, 99% yield).
