Reaktionsschritte

To a suspension of sodium methanethiolate (0.88 g) in dry DMF (15 ml) at 0° C. was added dropwise over 20 minutes a solution of 4-chloro-6-phenylpyrimidine (2.18 g) in dry DMF (25 ml). Ater stirring for a further 15 minutes, the temperature was allowed to rise to room temperature. After 2 hours the reaction mixture was poured into water and extracted with ether (×3). The combined ether extracts were washed with water (×2), dried, filtered and evaporated to give 4-methylthio-6-phenylpyrimidine (2.16 g, 87% pure by GC analysis) as a yellow liquid which was used directly in the next stage.
