실험 절차

{2-[2-(4-Benzo[d]isothiazol-3-yl-piperazin-1-yl)-ethyl]-phenyl}-isopropyl-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 three days, with the temperature ramped from 50° C. to 85° C. An additional 0.20 mmol of acetyl chloride was added after the second day. Polyamine scavenging resin was added (0.5 mmol). The solution was shaken overnight at room temperature, and filtered into an 8 mL vial. The reaction was concentrated via 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-isopropyl-acetamide was isolated in 100% purity @ 254 nm, LCMS (APCI): 423 [M+H]+.
