Reaction Conditions

Reaction Steps

{2-[2-(4-Benzo[d]isothiazol-3-yl-piperazin-1-yl)-ethyl]-phenyl}-methyl-amine was diluted to 0.20 M with anhydrous dichloroethane, then delivered to an 8 mL vial via pipette (0.20 mmol). To the amine solution was added base (0.4 M triethylamine in dichloroethane, 0.40 mmol). Acetyl chloride was diluted to 0.20 M with dichloroethane, and added at rt (0.2 mmol). The reaction was shaken overnight at 50° C., then evaluated by MS. Polyamine scavenging resin was added (0.5 mmol). The solution was shaken overnight at rt, then filtered into an 8 mL vial. The reaction was concentrated using an HT-12 GeneVac, then purified by HPLC (30×100 mm ODS-A C(18) 5u column). N-{2-[2-(4-Benzo[d]isothiazol-3-yl-piperazin-1-yl)-ethyl]-phenyl}-N-methyl-acetamide was isolated in 100% purity @ 254 nm, LCMS (APCI): 479 [M+H]+.
