Reaction Steps

A solution of 2.32 g (10 mmol) of ethyl 4-chloro-2-methylthiopyrimidine-5-carboxylate in 30 ml of 1,4-dioxan was treated with 1.4 ml (10 mmol) of triethylamine and 4.7 g (13 mmol) of 3-(tert-butyldiphenylsilyloxymethyl)aniline. The mixture was heated to 50° C. for 18 hours and then evaporated. The residue was partitioned between 50 ml of ethyl acetate and 50 ml of 2M aqueous hydrochloric acid. The organic phase was dried over magnesium sulfate, filtered and evaporated to afford 5.6 g (100%) of ethyl 4-[3-(tert-butyldiphenylsilyloxymethyl)anilino]-2-methylthiopyrimidine-5-carboxylate as a colorless oil. [Mass spectrum (ESI) MH+ =558].
