The procedure of Step 6 of Example 1 was repeated except for using 2-bromo-3-(3,5-difluorophenyl)-6-hydroxy-1H-inden-1-one obtained in Step 5 of Example 36 as a starting material instead of 2-bromo-6-hydroxy-3-phenyl-1H-inden-1-one, 2-(4-(methylsulfonyl)piperazin-1-yl)ethanol instead of 4-(2-hydroxyethyl)morpholine, being stirred for 4 d, and being purified by silica gel column chromatography (CH2Cl2/EtOAc=1:2) to obtain the title compound (99%)
