Reaction Steps

To a solution of 3-(6-(3-chlorophenyl)-5-isopentyl-1-methyl-2,4-dioxo-1,2-dihydropyrido[3,4-d]pyrimidin-3(4H)-yl)propyl formate and 3-(6-(3-chlorophenyl)-5-isopentyl-1-methyl-2,4-dioxo-1,2,7,8-tetrahydropyrido[3,4-d]pyrimidin-3(4H)-yl)propyl formate (21 mg, 0.047 mmol) in DCM (1 mL) was added MnO2 (40.8 mg, 0.47 mmol). The reaction was stirred at RT for 3 h then diluted with DCM (5 mL) and water (1 mL). The organic layer was washed with brine (1 mL), dried over Na2SO4, and concentrated to give 3-(6-(4-chlorophenyl)-5-isopentyl-1-methyl-2,4-dioxo-1,2-dihydropyrido[3,4-d]pyrimidin-3(4H)-yl)propyl formate (14 mg, 66.7% yield) as an oil. LCMS: MH+ 444 and TR=1.942 min. Used without further purification.
