Vorschrift

Compound 52 (50 mg, 0.114 mmol) was dissolved in methanol 30 mL, Pd/C 17 mg added and the reaction 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 53 was eluted at 24% ethyl acetate in hexane as half white coloured solid compound 2-(5-chloro-2-(trifluoromethyl)benzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 53. 1HNMR (400 MHz, CDCl3) δ ppm 7.43 (m, 3H), 7.18 (s, 1H), 6.82 (s, 1H), 3.90 (m, 3H), 3.87 (m, 4H), 3.48 (d, 1H), 3.38 (m, 1H), 3.17 (m, 4H), 3.09 (m, 1H), 2.95 (m, 1H), 2.67 (m, 2H); MS (ESI) m/z 440.0 (M+H).
