실험 절차

Following a procedure similar to that described in Example 2-2), but using 4-bromo-2-(4-fluorophenyl)-3-(pyridin-4-yl)thiophene prepared as described in 5) instead of 3-bromo-5-(4-fluorophenyl)-4-(pyridin-4-yl)pyrazole, and using (S)-1,2,3,5,6,7,8,8a-octahydroindolizin-7-one instead of (±)-1,2,3,5,6,7,8,8a-octahydroindolizin-7-one, the resulting product was subjected to a dehydration reaction as described in Example 3 and then treated by column chromatography through silica gel (eluent, ethyl acetate:methanol:isopropylamine=10:10:1), to give the title compound (Rf=0.50, 263 mg) as a brown amorphous solid (yield 23%).
