To a solution of 3-(3-(tert-butyldimethylsilyloxy)propyl)-5-((4-chlorophenyl)(hydroxy)methyl)-6-(2-isopropylphenyl)-1-methylpyrido[3,4-d]pyrimidine-2,4(1H,3H)-dione (15 mg, 0.0247 mmol) in HCOOH (1 mL) was added Zn dust (8 mg, 0.123 mmol). The reaction was heated at 50° C. for 1 h, cooled to RT then diluted with EA (5 mL) and water (1 mL). The organic layer was washed with brine (1 mL), dried over Na2SO4 and concentrated to a residue which was purified by Prep TLC eluted with PE/EA (2:1) to give 3-(5-(4-chlorobenzyl)-6-(2-isopropylphenyl)-1-methyl-2,4-dioxo-1,2-dihydropyrido[3,4-d]pyrimidin-3(4H)-yl)propyl formate (7 mg, 56% yield) as a colorless oil. LCMS: MH+ 506 and TR=2.225 min.
