(E)-2-(3-chloro-5-(trifluoromethyl)benzylidene)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one → 2-(3-chloro-5-(trifluoromethyl)benzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one

Participants

Reaction Steps

The 49 (30 mg, 0.068 mmol) was dissolved in methanol 20 mL, Pd/C 10 mg added 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 compound 50. The crude 50 was purified by flash chromatography using 100-200 mesh silica gel. The compound 2-(3-chloro-5-(trifluoromethyl)benzyl)-6-methoxy-5-morpholino-2,3-dihydro-1H-inden-1-one 50 was eluted at 28% ethyl acetate in hexane as half white coloured solid. 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), 3.37 (m, 1H), 3.17 (m, 4H), 3.09 (m, 1H), 2.96 (m, 1H), 2.70 (m, 2H); MS (ESI) m/z 440.0 (M+H).
