Reaction Steps

A solution of 2-amino-4-bromoquinoline (244 mg, 1.09 mmol) in THF (5 mL) at 0° C. was treated with NaH (96 mg, 60% dispersion in oil, 2.4 mmol), stirred for 30 min, treated with benzyl bromide (0.335 mL, 2.4 mmol), stirred at room temperature for 3 days, poured into water (30 mL), extracted with EtOAc (2×10 mL), dried (MgSO4), concentrated in vacuo, purified by chromatography [SiO2; heptane-EtOAc (10:1)] and the resulting solid recystallised (MeOH) to give the product (407 mg, 99%) as a white crystalline solid: IR νmax (Nujol)/cm−1 3059, 3020, 2955, 2925, 2854, 1609, 1592, 1542, 1498, 1455, 1426 and 1358; NMR δH (400 MHz, CDCl3) 4.89 (4H, s), 7.15 (1H, s), 7.20-7.68 (11H, m),7.56 (1H, t, J 7.0 Hz), 7.69 (1H, d, J 8.7 Hz) and 7.94 (1H, d, J 8.4 Hz).
