Procedure
8 g of 2-acetyl benzo[b]furan and 6 g of benzaldehyde are heated to boiling in 50 ml of methanol in the presence of 3 of concentrated hydrochloric acid. The batch is cooled after 10 h, and the precipitated yellow mass of crystals is filtered off by suction and rewashed with a small quantity of cold methanol.
Workup
- temperatureThe batch is cooled after 10 h
