The 157 (100 mg, 0.228 mmol) was dissolved in methanol and Pd/C (40 mg) added, the reaction stirred under hydrogen balloon for 6 h, filtered through celite bed and washed with excess methanol. The organic layer was concentrated to get the crude compound 158 which was purified by flash chromatography using 100-200 mesh silica gel. The compound was eluted at 10% ethyl acetate in hexane as half white coloured solid 2-(2-chloro-5-(trifluoromethyl)benzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 158. 1HNMR (400 MHz, CDCl3) δ ppm 7.43 (m, 3H), 7.20 (s, 1H), 6.84 (s, 1H), 3.89 (m, 7H), 3.54 (dd, 1H), 3.14 (m, 4H), 3.07 (m, 2H), 2.75 (m, 2H); MS (ESI) m/z 440.0 (M+H).
