Pyridine → Benzene, 1,1',1''-[(3-butynyloxy)methylidyne]tris-

Participants

Reaction Steps

Triphenylmethyl chloride (122 g, 0.44 mol) is added to a solution of but-3-yne-1-ol (25 g, 0.36 mol) in dichloromethane (400 ml) containing pyridine (50 ml) and stirred overnight at room temperature. The reaction mixture is filtered and washed with cold dilute hydrochloric acid, aqueous sodium bicarbonate and water. The dried solution is concentrated to a solid which is crystallized from ether-petroleum ether to give 4-triphenylmethyloxybut-1-yne (60 g), m.p. 97°-99° (ether-petroleum ether).
