To 27 (45 mg, 0.121 mmol), dissolved in methanol, was added Pd/C 20 mg and stirred under hydrogen balloon for 6 h. The reaction was filtered through celite bed and washed with excess methanol. The organic layer was concentrated to get the crude, which was purified by flash chromatography using 100-200 mesh silica gel. The compound was eluted at 23% ethyl acetate in hexane as half white coloured solid compound 2-(2,4-difluorobenzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 28. 1HNMR (400 MHz, CDCl3) δ ppm 7.18 (m, 2H), 6.82 (m, 3H), 3.88 (m, 3H), 3.86 (m, 4H), 3.31 (m, 1H), 3.16 (m, 4H), 3.06 (m, 1H), 2.95 (m, 1H), 2.73 (m, 2H); MS (ESI) m/z 373.9 (M+H).
