Reaction Steps

[4-Methoxy-7-(2-methyl-pyridin-4-yl)-benzothiazol-2-yl]-carbamic acid methyl ester (100 mg, 0.24 mmol) were dissolved in ethyleneglycol (3.0 ml) and treated with potassium hydroxide (528 mg, 1.1 mmol) and heated to 100° C. for 6.5 h. The reaction mixture was cooled to room temperature, diluted with water, neutralized with 1N HCl and extracted four times with ethyl acetate. The organic layers were combined and washed with water and saturated aqueous NaCl. The organic phases were then dried and the solvent removed in vacuo. The product was obtained as a light brown solid (83%). MS: m/e=272 (M+H+).
