Procedure

The procedure of Step 7 of Example 1 was repeated except for using 6-(2-morpholinoethoxy)-2-bromo-3-(4-(trifluoromethyl)phenyl)-1H-inden-1-one obtained in Step 6 of Example 32 as a starting material instead of 6-(2-morpholinoethoxy)-2-bromo-3-phenyl-1H-inden-1-one, 3,4-difluorophenylboronic acid instead of 3-pyridinylboronic acid, and being purified by prep HPLC (CH3CN/H2O=7:3) to obtain the title compound (31%).
