Procedure

tert-Butyl (2-bromo-1,3-benzothiazol-6-yl)carbamate (100 mg, 0.30 mmol) and tert-butyl [5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)pyridin-2-yl]methylcarbamate (0.146 g, 0.46 mmol) were subjected to the procedure used for the preparation of tert-butyl [5-(6-carbamoyl-1,3-benzothiazol-2-yl)pyridin-2-yl]methylcarbamate. This gave the product (110 mg) as a white solid. MS m/z (M−H) 455.
