反応手順
The procedure of Step 6 of Example 1 was repeated except for using 3-(3,5-difluorophenyl)-6-hydroxy-2-(pyridin-3-yl)-1H-inden-1-one obtained in Step 1 as a starting material instead of 2-bromo-6-hydroxy-3-phenyl-1H-inden-1-one, t-butyl 4-(3-hydroxypropyl)piperazine-1-carboxylate (2.0 eq) instead of 4-(2-hydroxyethyl)morpholine, using 2 equivalents of PPh3 and DIAD, and being stirred for 19 h to obtain the title compound (85%).
