反应详情

In 100 ml of ethanol were dissolved 10 g of 4-methoxycyclohexanone and 30 g of para-azidobenzaldehyde, after which a solution of 1 g of sodium hydroxide in 1 ml of water was added, and the resulting mixture was subjected to reaction in a brown flask at room temperature for 2 days. The crystals formed were separated by suction filtration, washed with ethanol, and then recrystallized from methyl Cellosolve to obtain 4.7 g of yellow crystals having a decomposition point of 145° to 150° C. (differential thermal analysis, the rate of heating: 5° C./min).
