Reaction Steps

2-(3-Dimethylaminocarbonylphenoxy)-4-(benzyl)amino-5-amino-6-(2-benzyloxy-5-cyanophenoxy)pyrimidine, a compound of formula (J), (0.26 g, 0.44 mmol), was treated with ethyl imidate hydrochloride (0.17 g, 1.3 mmol) in THF/ethanol at 80° C for 6 hours and then concentrated to an oil. The residue was heated in a sand bath under vacuum at 170° C. for 2.0 hours, cooled and filtered through a pad of silica, eluting with 5% methanol in methylene chloride. Evaporation of the volatiles afforded 0.20 g of 2-(3-dimethylaminocarbonylphenoxy)-6-(2-benzyloxy-5-cyanophenoxy)-8-methyl-9-benzylpurine, a compound of formula (L).
