A mixture of 2-(5,6-Dimethoxy-benzoimidazol-1-yl)-4-phenyl-thiazole-5-carbonitrile (261 mg, 0.72 mmol), sodium azide (220 mg) and ammonium chloride (250 mg) in N-methylpyrrolidone (2.5 ml) was stirred at 110° C. for 1 hr. Water was added and the mixture was extracted with methylene chloride. After removal of solvent, the residue was purified by HPLC to yield the product (138.1 mg, yield 47%). 1H-NMR (DMSO-D6) 8.78 (s, 1H); 8.21-8.29 (m, 2H); 7.86 (s, 1H); 7.36-7.50 (m, 3H); 3.90 (s, 3H); 3.88 (s, 3H). MS M/z 406 (M+1).
