Water → 4-(2-Butynyloxy)-6-phenylpyrimidine

Participants

Reaction Steps

In 5 ml of tetrahydrofuran were dissolved 186 mg of 4-chloro-6-phenylpyrimidine and 82 mg of 2-butyn-1-ol, to which 47 mg of sodium hydride (60% in oil) was added with stirring at room temperature, followed by further stirring for 3 hours. The reaction mixture was then poured into water and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated. The resulting residue was subjected to silica gel column chromatography to give 190 mg of 4-(2-butynyloxy)-6-phenylpyrimidine (the present compound (38)), m.p.: 59.6° C.
