Procedure

30 g of imidazole was dissolved in 80 ml of N,N-dimethylformamide. To this solution, 30 g of 3-bromo-2-heptanone was gradually added under stirring, and stirred at a temperature of from 50° to 60° C. for 4 hours. Then, the mixture was poured into water and extracted with chloroform. The extraction solution was treated by a usual manner, and the obtained oily product was purified by distillation, whereby 3-(imidazole-1-yl)-2-heptanone was obtained. The boiling point was 116°-119° C./2 mmHg.
