To a solution of 5-((4-chlorophenyl)(hydroxy)methyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)-6-(3-(trifluoromethoxy)phenyl)pyrido[2,3-d]pyrimidine-2,4 (1H,3H)-dione (100 mg, 0.162 mmol) in formic acid (3 mL) was added Zn dust (40.9 mg, 0.641 mmol). The reaction was heated at 50° C. for 2 h, cooled to RT and filtered. The filtrate was concentrated to a residue which was purified by Prep TLC eluted with PE/EA (1:1) to give 3-(5-(4-chlorobenzyl)-1-methyl-2,4-dioxo-6-(3-(trifluoromethoxy)phenyl)-1,2-dihydropyrido[2,3-d]pyrimidin-3(4H)-yl)propyl formate (50 mg, 56.5% yield) as a white solid. LCMS: MH+ 548 and TR=1.399 min.
