Reaction Steps

and 2-amino-4-methoxy-7-morpholin-4-yl-benzothiazol (1.0 g, 3.8 mmol), 4-(chloromethyl) benzoyl chloride (810 mg, 4.2 mmol) and pyridine (0.36 ml, 4.5 mmol) are reacted in dichloromethane (20 ml) for 18 h. The reaction is quenched with water (25 ml) and brought to pH 8.0 with sodium carbonate. The mixture is extracted with dichloromethane and the combined organic layers are dried and evapoarted to dryness. Flash chromatography (silica, eluent methylene chloride containing 2.5% methanol) affords the product as white crystalls in 54% yield. MS: m/e=418 (M+H+).
