Procedure

N-[4-(4-fluorophenyl)-5-(1-hydroxybut-3-enyl)-6-isopropyl-pyrimidin-2-yl]-N-methylmethanesulfonamide (4 g, 10.2 mmol) is diluted in 102 mL methanol. O3 gas is bubbled through the solution at −15° C. to −10° C. for 60 min. Reaction solution is bubbled with Argon for 2 min to remove the excess of O3. Dimethylsulfide (1.5 ml, 20.3 mmol) is added to the solution, maintaining stirring for 2 hours. Upon completion of the reaction, the solution is distilled under reduced pressure to remove the excess of dimethylsulfide and solvent. The residue is diluted in 200 mL dichloromethane, washed with DM water (50 mL), brine (50 mL) and dried over magnesium sulfate (1 g). The solvent is removed by distillation under reduced pressure to afford 4.1 g of N-[4-(4-fluorophenyl)-6-isopropyl-5-(3-oxoprop-1-enyl)pyrimidin-2-yl]-N-methylmethanesulfonamide.
