Reaction Conditions

Reaction Steps

Intermediate 29, ethyl 5-(benzoyloxy)-2-(2-(benzyloxycarbonyl)propan-2-yl)-6-oxo-1,6-dihydropyrimidine-4-carboxylate, (479 mg, 1 mmol) was dissolved in methanol and treated with H2 (1 atm) over 10% Pd/C (106 mg) for 1 hour. The reaction mixture was filtered through Celite and the solvent removed in vacuo. The remaining residue was dissolved in 2 mL of CH2Cl2 to which was added iPr2NEt (0.174 mL, 1 mmol) and chloroacetyl chloride (0.080 mL, 1 mmol). The resulting mixture was allowed to stir for 1 hour, then transferred to a seperatory funnel and washed with 1 N HCl. The organic layer was dried (Na2SO4) and the solvent removed to provide a solid. The solid (1 mmol) was dissolved in 4 mL of DMF. To this was added K2CO3 (140 mg, 1 mmol) and the resulting solution heated to 70° C. After stirring for 2 hours the reaction was quenched with 1 N HCl and transferred to a seperatory funnel. The mixture was washed with ethyl acetate which was then dried over Na2SO4. The solvent was removed in vacuo to provide the title compound as an oil.
