실험 절차
A mixture of 2-bromopyrimidine (3.96 g), 5-hexynol (2.44 g), dicylohexylamine (4 g), BTPC (250 mg), copper (I) iodide (25 mg) and acetonitrile (40 ml) was stirred at ambient temperature under nitrogen for 1 h (temp. rose to ~45°). Ether (120 ml) was added, the mixture was filtered and the filtrate was evaporated in vacuo to an oil which was purified by FCC. Elution with ether followed by System C (17:3) gave the title compound as a pale yellow oil (3.64 g), t.l.c. (System C 17:3) Rf 0.34.
