実験手順

A mixture of 987.5 mg of 2-bromo-3',4'-dihydroxy-5'-nitroacetophenone and 1.01 g of 2-aminopyridine is melted at 110°. After 30 minutes the melt is treated with 15 ml of ethanol and heated to boiling under reflux for 3 hours. The reaction mixture is then cooled to room temperature and the crystals are removed by filtration under suction. There is obtained 5-(imidazo[1,2-a]pyridin-3-yl)-3-nitropyrocatechol of m.p. 250°14 252° (from N,N-dimethylformamide/methanol).
