Reaction Steps

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 of Example 64 as a starting material instead of 2-bromo-6-hydroxy-3-phenyl-1H-inden-1-one, 3-methylbutan-1-ol (2.0 eq) instead of 4-(2-hydroxyethyl)morpholine, using 2 equivalents of PPh3 and DIAD, being stirred for 4 h, and being purified by prep. HPLC (20% H2O/CH3CN) to provide the title compound (59%).
