Sodium ethoxide → HCID 12451282, compound

Participants

Reaction Steps

To a stirred solution of 0.2 g (0.86 mmol) 2-amino-4-(methylthio)-6-phenyl-5-pyrimidinecarbonitrile in 10 ml ethanol was added 0.33 ml (0.89 mmol) sodium ethylate solution (2.7M in ethanol) and the mixture heated at reflux for 2 h. The reaction mixture was then concentrated in vacuo. The residue was partitioned between water and dichloromethane and the organic phase dried over sodium sulfate and concentrated in vacuo. Chromatography (ethyl acetate/hexane 1/1) afforded 60 mg (29%) 2-amino-4-ethoxy-6-phenyl-pyrimidine-5-carbonitrile as a white crystalline solid. MS m/e (%):240 (M+, 100), 239 ([M—H]+, 50), 170 (56).
