Procedure

Compound 15 (45 mg, 0.121 mmol) was dissolved in methanol and was added Pd/C 20 mg and stirred the reaction 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 compound 16. The crude 16 was purified by flash chromatography using 100-200 mesh silica gel. Compound 16 was eluted at 23% ethyl acetate in hexane as half white coloured solid 2-(4-chloro-2-fluorobenzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 16. 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 389.8 (M+H).
