Reaction Steps

To a solution of 1-(1,1-difluoroethyl)-3-nitrobenzene (1.00 g, 5.34 mmol) in methanol (5.0 mL) was added Pd/C (catalytic amount) and ethylene diamine (catalytic amount). The reaction mixture was subjected for hydrogenation in Parr apparatus under 30 psi for 5-6 h. The excess of solvent was removed under vacuum to afford 0.800 g of the desired product. 1HNMR (DMSO-d6): δ 1.88 (d, J=18.0 Hz, 3H), 3.74 (s, 1H), 7.72 (t, J=8.4 Hz, 1H), 6.81 (s, 1H), 6.87 (d, J=7.8 Hz, 1H), 7.19 (t, J=7.8 Hz, 1H).
