Reaction Steps

To a solution of 8-cyclopentyl-6-{5-(5-isobutyl-[1,3,4]oxadiazol-2-yl)-2-methyl-phenyl}-2-methylsulfanyl-8H-pyrido[2,3-d]pyrimidin-7-one (40.0 mg, 0.08 mmol) in dichloromethane (3 mL) at 0° C. was added 3-chloroperoxybenzoic acid (0.04 g, 0.19 mmol). The mixture was stirred at 0° C. for 1 hour, then was diluted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate solution and brine, dried (magnesium sulfate), filtered and concentrated under reduced pressure to give 8-cyclopentyl-6-{5-(5-isobutyl-[1,3,4]-oxadiazol-2-yl)-2-methyl-phenyl}-2-methanesulfinyl-8H-pyrido[2,3-d]pyrimidin-7-one (0.06 g). The crude product was used in the next step without further purification.
