实验步骤: 20.00 Grams of the 2-bromo-5-phenyl-1-penten-4-ol obtained above were dissolved in 160 g of N-methyl-2-pyrrolidone, and 11.20 g of sodium methylate were added. The mixture was allowed to react at 30° C. for 14 hours and then was neutralized with concentrated hydrochloric acid. Insolubles were filtered off, and the filtrate was concentrated under reduced pressure. The resultant oily substance was purified by silica gel column chromatography to give 9.96 g of 5-phenyl-1-pentyn-4-ol, nD25 =1.519, FI-MS m/e 160(M+), propargyl compound/allene compound 97.9/2.1. to react at 30° C. for 14 hours Insolubles were filtered off the filtrate was concentrated under reduced pressure The resultant oily substance was purified by silica gel column chromatography
