(6-Methoxypyridin-3-yl)boronic acid → 3-(3,5-Difluorophenyl)-2-(6-methoxypyridin-3-yl)-6-[2-(1,1-dioxothiomorpholin-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-(1,1-dioxothiomorpholin-4-yl)ethoxy]-1H-inden-1-one obtained in Step 1 of Example 92 as a starting material instead of 6-(2-morpholinoethoxy)-2-bromo-3-phenyl-1H-inden-1-one, 6-methoxy-3-pyridinylboronic acid instead of 3-pyridinylboronic acid, and being purified by silica gel column chromatography (EtOAc/CH2Cl2=1:1) to obtain the title compound (68%).
