반응 단계

To a suspension of NaH (60% in mineral oil, 340 mg) in dry DMF (75 ml) at 0° C. was added the preceding pyridinone (1.0 g) and the mixture was stirred at 0° C. for one half hour. To the resulting suspension was added 1-bromo-2-pentyne (750 mg) dropwise. The resulting mixture was kept at 0° C. for one half hour and poured into saturated aqueous ammonium chloride (200 ml). The aqueous suspension was extracted with ether (3×100 ml), the combined ether layers washed with brine and dried, yielding the crude product. Trituration with hexane yielded the product as a yellow solid.
