Procedure

To a stirred solution of 2-chloroethyl-N-({4-[(9-fluoro-5,6-dihydro-4H-benzo[6,7]-cyclohepta[d][1,3]thiazol-2-yl)amino]-cyclohexyl}methyl)carbamate (5.4 g, 11.95 mmol) in 100 ml anhydrous DMF was added NaH (60% in mineral oil) (0.6 g, 15.0 mmol). TLC (EtOAc) indicated that the reaction had proceeded to approximately 40% completion after 15 minutes. An additional 0.58 g (14.5 mmol) NaH (60% in mineral oil) was added and the solution was stirred at room temperature for another 15 minutes. TLC indicated the reaction was complete. The solution was poured into water (500 ml) and was extracted with EtOAc. The extract was separated and evaporated to yield a dark viscous oil. The oil was chromatographed on silica-gel eluting with 2:1 EtOAc/hexane to yield a white solid. The solid was dissolved in 40 ml CHCl3 and 10 ml 1N HCl in Et2O was added to the solution. The volatiles were removed and the resulting solid was triturated with Et2O. The solution was filtered and the slightly tan solid washed with ether and dried to yield 52% (2.83 g) of the desired product as the HCl salt: 1H-NMR (Free-base) (CDCl3) δ 1.16 (4H, m), 1.60 (1H, m), 1.80 (2H, m), 2.05 (2H, m), 2.22 (2H, m), 2.81 (4H, m), 3.12 (2H, d, J=7.3 Hz), 3.27 (1H, m), 3.57 (2H, t, J=8.2 Hz), 4.33 (2H, t, J=8.0 Hz), 5.05 (1H, d, J=7.7 Hz), 6.83 (1H, dt, J=2.7, 8.2 Hz), 7.05 (1H, m), 7.68 (1H, dd, J=2.7, 10.8 Hz). m.p. (HCl salt) 223-225° C. Anal. Calcd. For C22H27N3ClFO2S: C, 58.5; H, 6.0; N, 9.3. Found: C, 58.43; H, 6.06; N, 9.38; 416 (ESMS, MH+).
