Procedure

To a solution of 4-bromomethyl-6-methoxy-2-(4-methoxy-phenyl)-benzothiazole (0.47 g, 1.29 mmol) in ethanol (6 mL) was added a solution of potassium cyanide (0.1 g, 1.54 mmol) in water (0.5 mL). The mixture was refluxed for 1.5 h, then cooled to room temperature. Ethanol was evaporated and the mixture was extracted with ethylacetate. After chromatographic purification gave 4-cyanomethyl-6-methoxy-2-(4-methoxy-phenyl)-benzothiazole as a yellow solid (0.29 g, 73% yield). Mass spec: MH+=311.
