Participants

Reaction Steps

A solution of 4.25 g (18.26 mmol) of ethyl 4-chloro-2-methylthio-pyrimidine-5-carboxylate, 4.73 g (22.85 mmol) of 4-(tetrahydropyran-2-yloxymethyl)aniline and 6.4 ml (45.7 mmol) of triethylamine in sieve-dried 1,4-dioxan was heated at 60° C. for 4 hours. The reaction mixture was evaporated and the residue partitioned between ethyl acetate and water. The ethyl acetate layer was separated, dried (MgSO4) and evaporated to give a brown oil which was purified by flash chromatography on silica gel using1:4 ethyl acetate/hexane as eluent. Product containing fractions were combined and evaporated to give 6.68 g (90%) of ethyl 4-[4-(tetrahydropyran-2-yloxymethyl)phenyl]amino-2-methylthiopyrimidine-5-carboxylate as a yellow oil. [Mass spectrum (ESI) MH+ =404].
