Reaction Steps

N1-(9-fluoro-5,6-dihydro-4H-benzo[6,7]cyclohepta[d][1,3]thiazol-2-yl)-5-aminopentanamide (115 mg, 0.34 mmole) was dissolved in 2 ml of dry THF, cooled with an ice bath, triethylamine was added (96 μl, 0.69 mmole) followed by addition of 27 μl of methane sulfonyl chloride (0.35 mmole). The reaction mixture was stirred at room temperature for 6 hours, quenched with saturated sodium carbonate solution and extracted with 3×3 ml of ethyl acetate. The combined ethyl acetate extracts were washed with saturated sodium chloride solution, concentrated and chromatographed (12 g of silica gel, EtOAc/hexanes/7N NH3 in MeOH, 50:50:2) to give 53 mg of the desired product as a white solid (38%): m.p. 145-147° C.; 412 (ESMS, MH+).
