Ethanethiol → Methyl 2-chloro-6-(ethylthio)pyrimidine-4-carboxylate

Participants

Reaction Steps

A solution of ethanethiol (0.30 g, 4.8 mmol) in THF (1 ml) was added dropwise to a solution of methyl 2,6-dichloropyrimidine-4-carboxylate (1 g, 4.8 mmol), THF (8 ml) and TEA (0.49 g, 4.8 mmol) at 0° C. under nitrogen. The mixture was stirred for 2 h and slowly warmed to room temperature. The mixture was diluted with EtOAc (50 ml) and water (10 ml). The organic layer was separated, dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (1.1 g).
