Procedure

0.1 g of 4-methoxy-7-[2-(6-methyl-pyridin-3-yl)-thiazol-4-yl]-benzothiazol-2-ylamine (0.00028 Mol) were dissolved in dioxane (2 ml) and treated with 0.047 ml triethylamine (0.00034 Mol) and 0.164 ml of phosgene (20% in toluene) (0.00031 Mol). After stirring for 2 hrs. at room temperature 0.122 ml of morpholine (0.0014 Mol) were added and the whole mixture was stirred for 16 hrs. at ambient temperature. Upon addition of water (5 ml) a precipitation formed, which was filtered, washed with water and dried. This crude material was triturated with hot MeOH and after cooling to room temperature filtered. The filtrate was evaporated and the residue subjected to column chromatography (silicagel, CH2Cl2/MeOH+1% NH4OH). The title compound was obtained as a light yellow solid (7%); MS (ISP): m/e=468 (M+H+).
