Reaction Steps

2-(2-Benzyloxy-5-cyanophenoxy)-4-(ethoxycarbonylmethyl)amino-5-nitro-6-(3-(dimethylaminocarbonyl)phenoxy)pyrimidine (1.1 g, 1.80 mmol), a compound of formula (H), and granular zinc (0.5 g) were mixed with tetrahydrofuran (50 mL) and 10% aqueous HCl (10 mL). The reaction mixture was heated for 30 minutes at 70° C. The volatiles were evaporated. Saturated aqueous NaHCO3 was added and the solution extracted with ethyl acetate (300 mL). The organic layer was dried (Na2SO4) and evaporated to afford 1.35 g of 2-(2-benzyloxy-5-cyanophenoxy)-4-(3-(dimethylaminocarbonyl)phenoxy)-1,7-dihydro-6(5H)-pteridinone, a compound of formula (J).
