Procedure
Compound 73 (1.0 g, 2.296 mmol) was dissolved in methanol 250 mL, Pd/C 400 mg was added, and the reaction was stirred under hydrogen balloon for 6 h. The result was filtered through celite bed and washed with excess methanol. The organic layer was concentrated to get the crude compound 74, which was purified by flash chromatography using 100-200 mesh silica gel. The compound was eluted at 30% ethyl acetate in hexane as half white coloured solid 6-methoxy-5-morpholino-2-(4-((trifluoromethyl)thio)benzyl)-2,3-dihydro-1H-inden-1-one 74. 1HNMR (400 MHz, CDCl3) δ ppm 7.56 (d, 2H), 7.28 (d, 2H), 7.18 (s, 1H), 6.81 (s, 1H), 3.89 (m, 3H), 3.87 (m, 4H), 3.37 (dd, 1H), 3.15 (m, 4H), 3.06 (m, 1H), 2.96 (m, 1H), 2.66 (in, 2H); MS (ESI) m/z 438.0 (M+H).
