Reaction Steps

To a stirred, septum capped solution of trans-N2-[4-(aminomethyl)cyclohexyl]-9-fluoro-5,6-dihydro-4H-benzo-[6,7]cyclohepta[d][1,3]thiazol-2-amine (0.165 g, 0.394 mmol) in 3.0 ml anhydrous pyridine was added 0.034 ml (0.038 g, 0.48 mmol) acetyl chloride dropwise. Stirring at room temperature was continued for 90 minutes and the solution was then poured into 50 ml water and extracted with EtOAc (2×50 ml). The combined extracts were evaporated to yield 0.126 g of the crude product as a viscous golden oil. The oil was chromatographed on preparative TLC eluting with EtOAc to yield 28% (0.042 g) of the desired product as a white solid: 1H-NMR (CDCl3) δ 1.13 (4H, m), 1.43 (1H, m), 1.80 (2H, m), 1.98 (3H,s), 2.05 (2H, m), 2.21 (2H, m), 2.80 (4H, m), 3.10 (2H, t, J=6.5 Hz), 3.24 (1H, m), 5.00 (1H, d, J=7.8 Hz), 5.75 (1H, m), 6.81 (1H, dt, J=2.8, 8.2 Hz), 7.04 (1H, m), 7.69 (1H, dd, J=2.7, 10.8 Hz); m.p. 88-91° C.
