Reaction Steps
To a cold solution of 2-hydroxy-5-nitro pyridine (0.500 g, 3.57 mmol) in DMF (4.0 mL) was added cyclopropyl methyl bromide (0.481 g, 3.57 mmol) at 0° C. The reaction mass was stirred at RT for 5-6 h. The reaction mass was quenched in water and extracted with ethyl acetate. The organic layer was separated, dried over anhydrous sodium sulphate and concentrated. The obtained crude was purified by column chromatography on neutral alumina eluting with 10% EtOAc: Pet.ether to afford 0.200 g of the desired product. 1HNMR (DMSO-d6): δ 0.45-0.48 (m, 2H), 0.70-0.75 (m, 2H), 1.10-1.28 (m, 1H), 3.87 (d, J=7.2 Hz, 2H), 6.57 (d, J=10.2 Hz, 1H), 8.10 (dd, J=3.0 Hz & 2.4 Hz, 1H), 8.77 (s, 1H).
