Procedure
2-[5-Acetyl-3,6-dimethyl-2-oxo-1-(3-trifluoromethyl-phenyl)-1,2,3,4-tetrahydro-pyrimidin-4-yl]-5-cyano-benzoic acid acetyl hydrazide (intermediate 13) (15 mg, 0.03 mmol) is suspended in dichloromethane (1 mL) and (methoxycarbonylsulfamoyl)triethyl-ammonium hydroxide (Burgess reagent)(17.4 mg, 0.07 mmol) is added. The mixture is stirred at room temperature for 3 days. The solvent is removed under reduced pressure and purification is performed by reversed phase HPLC. Yield: 6.4 mg; ESI mass spectrum [M+H]+=496; Retention time HPLC: 1.04 min (HPLC method Z018_S04).
