The 85 (50 mg, 0.123 mmol) was dissolved in methanol 20 mL, Pd/C 20 mg added, and the reaction stirred under hydrogen balloon for 6 h, then filtered through celite bed and washed with excess methanol. The organic layer was concentrated to get the crude 86 which was purified by flash chromatography using 100-200 mesh silica gel. The compound 86 was eluted at 25% ethyl acetate in hexane as half white coloured solid compound 6-methoxy-5-morpholino-2-(4-(trifluoromethyl)benzyl)-2,3-dihydro-1H-inden-1-one 86. 1HNMR (400 MHz, CDCl3) δ ppm 7.53 (d, 2H), 7.34 (d, 2H), 7.18 (s, 1H), 6.80 (s, 1H), 3.89 (m, 3H), 3.86 (m, 4H), 3.38 (m, 1H), 3.15 (m, 4H), 3.08 (m, 1H), 2.96 (m, 1H), 2.68 (m, 2H); MS (ESI) m/z 406.0 (M+H).
