Reaction Steps

To a stirred solution of N2-[4-(aminomethyl)cyclohexyl]-4,5-dihydrobenzo[2,3]-oxepino[4,5-d][1,3]thiazol-2-amine (0.600 g, 1.49 mmol) in anhydrous pyridine (3 ml) and diisopropylethylamine (3 ml) was added propionyl chloride (0.144 ml, 1.66 mmol) dropwise. The solution was stirred for 20 minutes at room temperature and then poured into water (50 ml) and extracted with EtOAc. The solvent was removed and the residue chromatographed on silica-gel eluting with EtOAc to yield 70% (402 mg) of the product as a light yellow solid: 1H-NMR (CDCl3) δ 1.12 (6H, m), 1.50 (1H, m), 1.65 (1H, m), 1.85 (2H, d, J=12.1 Hz), 2.22 (4H, m), 3.16 (4H, t, J=5.3 Hz), 3.32 (1H, m), 4.33 (2H, t, J=5.2 Hz), 4.81 (1H, m), 5.49 (1H, m), 7.00 (1H, d, J=8.5 Hz), 7.15 (2H, m), 8.25 (1H, d, J=8.1 Hz). m.p. 56-60° C. FAB+ m/z=386 (MH+).
