Reaction Steps

To a solution of 3-(3-((1-(2-fluoro-4-iodophenyl)-3-(4-methoxybenzyl)-6,8-dimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydropyrido[2,3-d]pyrimidin-5-yl)amino)phenyl) propanamide (1b) (1.7 gm, 2.396 mmol) in THF (8 ml) was added sodium methoxide (30% solution in MeOH) (0.431 mg, 2.396 mmol) at 0° C. The reaction mixture was stirred at room temperature for 2 hr and quenched by addition of 2N HCl solution. The resulting mixture was concentrated under vacuum and residue was re-crystallized in IPA, methanol and water to yield the titled compound (1c) (1.5 g, 88%) [m/z=710.20 (M+1)].
