Procedure
To a solution of (R)-1-((S)-1-(4-bromophenyl)ethyl)-4-(4-fluorophenyl)-4-(3-hydroxypropyl)tetrahydropyrimidin-2(1H)-one (50 mg, 0.12 mmol) and triethylamine (161 mg, 1.59 mmol) in CH2Cl2 (5 mL) was added methanesulfonyl chloride (91 mg, 0.8 mmol) at 0° C., and the reaction mixture was stirred at rt till the reaction was over. The reaction was quenched with H2O, and the mixture was extracted with EtOAc. The organic phase was washed with brine, dried over Na2SO4, filtered and concentrated to give crude 3-((R)-1-((S)-1-(4-bromophenyl)ethyl)-4-(4-fluorophenyl)-2-oxohexahydropyrimidin-4-yl)propyl methanesulfonate (58 mg, 95%), which was used for the next step without further purification.
