Ethylenediamine → 6-(Cyclopropylmethoxy)pyridin-3-amine

Participants

Reaction Steps

To a solution of 2-(cyclopropylmethoxy)-5-nitropyridine (2.0 g) in ethanol (10.0 mL) was added Pd/C (0.500 g) and ethylene diamine (5.0 mL). The reaction mixture was subjected for hydrogenation in Parr apparatus under 40 psi for 2-3 h. The reaction mass was quenched in water and extracted with DCM and concentrated the organic layer to afford 0.400 g of the desired product. 1HNMR (CDCl3): δ 0.31-0.32 (m, 2H), 0.43-0.46 (m, 2H), 1.07-1.12 (m, 1H), 3.62 (d, J=6.6 Hz, 2H), 4.25 (s, 2H), 6.24 (d, J=6.6 Hz, 1H), 6.89 (s, 1H), 7.05 (dd, J=3.0 Hz & 2.4 Hz, 1H); MS [M+H]+: 165.13.
