To a solution of 2-amino-N-(2-phenylpyrimidin-5-yl)-5-(piperidin-1-yl)benzamide (2 g, 3.75 mmol, 1.00 equiv, 70%) in dichloromethane (30 mL) was added 3-(methoxycarbonyl)benzoic acid (1160 mg, 6.12 mmol, 1.20 equiv, 95%), EDC.HCl (2040 mg, 10.20 mmol, 2.00 equiv, 95%), and 4-dimethylaminopyridine (660 mg, 5.14 mmol, 1.00 equiv, 95%) and the resulting solution was stirred for 3 h at 25° C. in an oil bath. The mixture was concentrated under vacuum, diluted with 100 mL of ethyl acetate, washed with 1×100 mL of brine and then the organic layer was concentrated under vacuum. The residue was applied onto a silica gel column and eluted with petroleum ether/ethyl acetate (2:1) to afford 1200 mg (60%) of product as a green to yellow solid.
