実験手順
A mixture of 3-butyn-1-ol (5.0 g), (4-bromobutyl)benzene (15.0 g), aqueous sodium hydroxide (30 ml, 50% w/v), and TAB (0.6 g) was stirred vigorously for 3 days, treated with water (100 ml) and extracted with ER (2×200 ml). The dried extract was evaporated and the residue was purified by FCC eluting with CX-ER 19:1 to give the title compound as a colourless oil (9.5 g). T.l.c. (CX-ER 9:1) Rf 0.45.
