실험 절차

Following the procedure of Example 1c and using 14.7 g (100 mmol) of 3,5-dimethyl-4-hydroxybenzonitrile and substituting 5-chloro-1-pentyne (12.7 mL, 120 mmol) for the product of Example 1b, there was obtained a red-brown oil which was purified by chromatography (Silica Gel 60, 15% ethyl acetate in hexanes) to give pure title compound (21.2 g, 99.4%) as a pale yellow oil.
