2-[5-Acetyl-3,6-dimethyl-2-oxo-1-(3-trifluoromethyl-phenyl)-1,2,3,4-tetrahydro-pyrimidin-4-yl]-5-cyano-benzoic acid (intermediate 6) (70 mg, 0.15 mmol) and triethylamine (35 μL, 0.25 mmol) are suspended in N,N-dimethylformamide (1.5 mL) and the mixture is shaken for 5 min. A solution of O-(7-azabenzotriazole-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (61.1 mg, 0.16 mmol) in N,N-dimethylformamide (0.5 mL) and triethylamine (35 μL, 0.25 mmol) is added and the reaction mixture is shaken for 1.5 h at room temperature. The product is purified by reversed phase HPLC. Yield 48 mg; ESI mass spectrum [M+H]+=495; Retention time HPLC: 0.99 min (HPLC method Z011_S03).
