To a stirred solution of methyl 2-chloro-4-[4-(piperidin-1-yl)pyrimidin-2-yl]-1,3-thiazole-5-carboxylate (Intermediate 67, 30 mg, 0.08 mmol) in N-methylpyrrolidinone (0.5 mL), N,N-diisopropyl ethylamine (23 mg, 0.18 mmol) and 3,4-dichloro-N-[(3S,4R)-3-methoxypiperidin-4-yl]-5-methyl-1H-pyrrole-2-carboxamide (WO2006087543, 27 mg, 0.09 mol) were added at room temperature. The above reaction mixture was heated at 90° C. for 3 h. The reaction mixture was cooled to room temperature, diluted with water (5 mL) and stirred for 1 h. The solid obtained was collected by filtration and dried to obtain methyl 2-[(3S,4R)-4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl]-4-[4-(piperidin-1-yl)pyrimidin-2-yl]-1,3-thiazole-5-carboxylate 35 mg (66%).
