Procedure
N-{4-[3-(4-1,2-Benzoisothiazol-3-yl-piperazin-1-yl)-propyl]-phenyl}-2-thiophen-2-yl-acetamide was prepared according to the procedure outlined in Example 1, starting with 4-[3-(4-1,2-benzisothiazol-3-yl-piperazin-1-yl)-propyl]-phenylamine (200 mg) and 2-thiopheneacetyl chloride (0.069 mL). The resultant white solid was purified using an ISCO autocolumn eluting with 80% ethyl acetate in hexanes. N-{2-[3-(4,1,2-Benzoisothiazol-3-yl-piperazin-1-yl)-propyl]-phenyl}-2-(4-chloro-phenyl)-acetamide was isolated in 100% purity @ 254 nm; LCMS (APCI): 477 [M+H]+.
