Procedure

2-(3,6-Dichloro-pyridin-2-yl)-1H-benzoimidazole (20 mg; 0.076 mmol) was dissolved in ethanol (1.5 ml) and concentrated ammonia (2 ml) in a pressure tube. After 1000 minutes in a microwave at 140° C. and 200 psi, the solvents were removed and the residue dissolved in isopropyl alcohol (1 ml) and concentrated ammonia (1 ml) before microwaving as before. The solvents wore evaporated and the residue chromatographed on silica gel with 80% ethyl acetate in heptane to give 6-(1H-benzoimidazol-2-yl)-5-chloro-pyridin-2-ylamine (4 mg, 21%).
