6-Methoxypyridine-2-boronic acid → 3-(3,5-Difluorophenyl)-2-(6-methoxypyridin-3-yl)-6-{2-[1-(methylsulfonyl)piperidin-4-yl]ethoxy}-1H-inden-1-one

Participants

Reaction Steps

The procedure of Step 7 of Example 1 was repeated except for using 2-bromo-3-(3,5-difluorophenyl)-6-{2-[1-(methylsulfonyl)piperidin-4-yl]ethoxy}-1H-inden-1-one obtained in Step 3 as a starting material instead of 6-(2-morpholinoethoxy)-2-bromo-3-phenyl-1H-inden-1-one, 6-methoxypyridinylboronic acid instead of 3-pyridinylboronic acid, and being purified by silica gel column chromatography (EtOAc/CH2Cl2=1:1) to obtain the title compound (59%).
