Reaction Steps

To a stirred solution of N1-{4-[(4,5-dihydrobenzo[2,3]oxepino[4,5-d][1,3]thiazol-2-ylamino)methyl]cyclohexyl}propanamide (0.405 g, 1.05 mmol) in anhydrous THF (4 ml) was added 1M BH3 in THF (5.5 ml, 5.5 mmol). The solution was stirred at room temperature for 52 hours. 4N HCl (12 ml) was added slowly and stirring continued for 30 minutes thereafter. The solution was poured into 2N NaOH (60 ml) and extracted with EtOAc. The extract was washed with 10% brine, separated and evaporated to yield 77% (300 mg) of the amine as a viscous golden oil: 1H-NMR (CDCl3) δ 0.88 (3H, t), 1.06 (2H, m), 1.38 (2H, m), 1.49 (2H, m), 1.80 (6H, m), 2.40 (1H, m), 2.58 (2H, t), 3.15 (2H, m), 3.63 (2H, t), 4.30 (2H, t), 5.12 (1H, m), 6.98 (1H, d), 7.11 (2H, m), 8.23 (1H, dd); 400 (ESMS, MH+).
