Reaction Steps

N-(4-Benzyloxy-7-morpholin-4-yl-benzothiazol-2-yl)-4-chloromethyl-benzamide (1.0 g, 2.0 mmol) were dissolved in CH2Cl2 (10 ml) and treated at −78° C. with tetrabutyl ammonium iodide (0.95 g, 2.6 mmol) and a solution of boron trichloride in CH2Cl2 (1M, 7.4 ml). After subsequent warming to 0° and stirring for additional 2 h, ice (2 g) and then water (10 ml) and methanol (2 ml) were added and the phases separated. The aqueous phases were extracted twice with CH2Cl2/MeOH, the combined organic layers were dried with Na2SO4 and evaporated to dryness. Recrystallization from CH2Cl2/MeOH afforded the title compound as an off-white solid (18%). MS: m/e=403 ([M−H+]−).
