Reaktionsschritte

To a solution of N-(2-piperazinylethyl)[4-(trifluoromethyl)phenyl]carboxamide (0.2 g, 0.38 mmol) in ethanol was added diisopropyl ethylamine (0.25 ml, 1.5 mmol) and 5-[((2R)oxiran-2-yl)methoxy]-2-methylbenzothiazole (0.09 g, 0.42 mmol). The reaction was heated to 85 degrees for four hours. The mixture was then concentrated in vacuo and purified using preparative thin layer chromatography (10:1 DCM:MeOH) to yield N-(2-{4-[(2R)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl]piperazinyl}ethyl)[4-(trifluoromethyl)phenyl]carboxamide (M+1=523.0).
