Reaction Steps

To a solution of N2-{4-[(propylamino)methyl]cyclohexyl)-4,5-dihydrobenzo[2,3]oxepino[4,5-d][1,3]thiazol-2-amine (0.254 g, 0.68 mmol) in anhydrous THF (4 ml) was added 1H-benzotriazole-1-carboxaldehyde (0.110 g, 0.75 mmol). The solution was stirred at room temperature for 1 hour and then poured into 2N NaOH (50 ml) and extracted with EtOAc (60 ml). The extract was separated and evaporated to yield 295 mg of a viscous oil. Chromatography on silica-gel eluting with 1:1 EtOAc/hexane yielded 56% (152 mg) of the product as a white solid: 1H-NMR (CDCl3) δ 0.90 (3H, m), 1.14 (4H, m), 1.58 (2H, m), 1.78 (2H, m), 2.23 (2H, m), 3.20 (8H, m), 4.32 (2H, t, J=4.9 Hz), 5.03 (1H, m), 6.99 (1H, m), 7.12 (2H, m), 8.01 (0.5H, s), 8.11 (0.5H, s), 8.22 (1H, d); m.p. 53-55° C.; 400 (ESMS, MH+).
