Reaction Steps

To a solution of 5-(1-hydroxy-3-methylbutyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy) propyl)-6-(3-(trifluoromethoxy)phenoxy)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (See Compound 46, step 2, 60 mg, 0.103 mmol) in HCOOH (4 mL) was added Zn dust (34 mg, 0.515 mmol). The reaction was heated at 100° C. for 3 h, cooled to RT and filtered. The filtrate was concentrated and dried to give 3-(5-isopentyl-1-methyl-2,4-dioxo-6-(3-(trifluoromethoxy)phenoxy)-1,2-dihydropyrido[2,3-d]pyrimidin-3(4H)-yl)propyl formate (50 mg, 96.1% yield) as a solid. LCMS: MH+ 510 and TR=2.446 min. Used without further purification.
