Reaction Steps

A suspension of 5.3 g of 1-butyn-3-ol and 5 g of 1-naphthoyl chloride is cooled to -10° C. and 3.1 ml. of 35% sodium hydroxide are slowly added dropwise. The mixture is warmed to room temperature and stirred until it is neutral. The mixture is poured into ice-water and then extracted with ether. The ether solution is washed with 10% sodium hydroxide and with water and dried. After the ether is distilled off, the residue is recrystallized from methanol to yield 1-methyl-2-propynyl 1-naphthoate, m.p. 66°-68° C.
