3-((dimethylamino)methyl)-N-(4'-fluoro-4-nitro-[1,1'-biphenyl]-3-yl)azetidine-1-carboxamide → N-(4-amino-4'-fluoro-[1,1'-biphenyl]-3-yl)-3-((dimethylamino)methyl)azetidine-1-carboxamide

Reaction Steps

To a solution of 3-((dimethylamino)methyl)-N-(4′-fluoro-4-nitro-[1,1′-biphenyl]-3-yl)azetidine-1-carboxamide (1.7 g, 4.57 mmol, 1.0 eq.) in methanol (100 mL) and was added 10% Pd/C (1.0 g, 0.94 mmol). The reaction mixture was stirred 2 h under a hydrogen atmosphere. The reaction was then filtered and the filtrate was concentrated under reduced pressure to give N-(4-amino-4′-fluoro-[1,1′-biphenyl]-3-yl)-3-((dimethylamino)methyl)azetidine-1-carboxamide (35 mg, 3% yield) as an off-white solid. ESI+ MS: m/z 343 ([M+H]+), 1HNMR (500 MHz, DMSO-d6): δ 7.61 (s, 1H), 7.53-7.51 (m, 2H), 7.36 (d, J=2.0 Hz, 1H), 7.21-7.15 (m, 3H), 6.76 (d, J=8.5 Hz, 1H), 4.98 (s, 2H), 3.99 (t, J=8.0 Hz, 2H), 3.58 (dd, J12=6.0 Hz, J13=8.0 Hz, 2H), 2.72-2.69 (m, 1H), 2.45-2.44 (m, 2H), 2.13 (s, 6H).
