Separetely, 16 g of potassium t-butoxide was dissolved in 21 ml of dry dimethyl sulfoxide (hereinafter "DMSO"), and a solution of 1.9 g of the above prepared dibromide in 5 ml of DMSO was added thereto over 10 minutes, followed by heating at 50° C. for 1 hour. The reaction mixture was poured into 100 ml of water and extracted with diethyl ether. The extract was washed successively with water and a saturated sodium chloride aqueous solution, and dried. After filtration, the filtrate was concentrated under reduced pressure to obtain 1.5 g of an acetylene triacetate compound.
