Reaktionsschritte

Mix (2-benzothiazolyl)(4-piperidinyl)methanone.CF3CO2H (331 g, 9.19 mmol), 2-(4-methoxyphenyl)ethyl bromide (2.07 g, 9.64 mmol), potassium carbonate (3.33 g, 24.1 mmol) and dimethylformamide (35 mL) and heat at 90° C. overnight. Cool to room temperature and partition between a 2:1 mixture of ethyl acetate/toluene and water. Separate the aqueous phase and wash the organic phase with water and brine. Dry (MgSO4) and evaporate the solvent in vacuo. Purify by chromatography (30% ethyl acetate/hexane) and recrystallize (cyclohexane) to give the title compound as a tan powder; mp 119°-120° C.
