実験手順

To 1.0 g (3.4 mmole) of 2-(4-mercaptophenyl)-3-(4-pyridyl)-6,7-dihydro-[5H]-pyrrolo[1,2-a]imidazole prepared as in Example 16 in 50 ml methylene chloride at 0° C. was added a solution of 0.3 g (3.7 mmole, 0.26 ml) acetyl chloride in 10 ml CH2Cl2 over a period of 10 minutes. The reaction was allowed to come to room temperature and was stirred for 30 minutes. The mixture was then diluted with methylene chloride and washed with 3N NaHCO3, saturated NaCl, treated with Na2SO4, stripped, then flash chromatographed on silica with methylene chloride containing 1% to 5% MeOH. The isolated material was recrystallized twice from ethyl acetate to give 0.20 g of the titled compound. 17.6% yield, mp 152°-154° C. C19H17N3OS, Calculated, C: 68.03, H: 5.11, N: 12.53; Found, C: 68.25, H: 5.40, N: 12.14.
