To a solution of 3-(3-(tert-butyldimethylsilyloxy)propyl)-6-(3-chlorophenyl)-5-(1-hydroxy-3-methylbutyl)-1-methylpyrido[3,4-d]pyrimidine-2,4(1H,3H)-dione (30 mg, 0.055 mmol) in HCOOH (1 mL) was added Zn dust (35.6 mg, 0.55 mmol). The reaction was heated at 50° C. for 1 h, cooled to RT and diluted with EA (5 mL) and water (1 mL). The organic layer was washed with brine (1 mL), dried over Na2SO4 and concentrated to give 3-(6-(3-chlorophenyl)-5-isopentyl-1-methyl-2,4-dioxo-1,2-dihydropyrido[3,4-d]pyrimidin-3(4H)-yl)propyl formate. LCMS MH+ 444 and TR=1.738 min 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. LCMS: MH+ 446 and TR=1.956 min, (21 mg, 70% yield) as a solid. Used without further purification.
