Benzaldehyde → HCID 73851444, compound

Participants

Reaction Steps

A mixture of 13 (34.6 g, 154 mmole), benzaldehyde (17.4 g, 164 mmole) and NaOH (6.5 g, 164 mmole) in EtOH (400 ml) was refluxed for 3 hours. After cooling the reaction mixture to room temperature, the resulting yellow crystal was collected by filtration and washed with cold EtOH and dried in vacuo to give 14 (38.4 g, 128 mmole). The filtrate was concentrated under reduced pressure to give a second crop (3.3 g, 11 mmole) (total 41.7 g, 139 mmole, 90%).
