Reaction Steps
1.1 kg/h of a 1M solution of 2,3-difluorophenetole containing 10 mol % of 2,2,6,6-tetramethylpiperidine were introduced into a continuous-flow reactor and mixed with 0.4 kg/h of a 2.5M solution of hexyllithium in hexane at −35° C. After the mixture had passed through the reaction zone, 0.28 kg/h of a 4.7M solution of benzaldehyde in THF were mixed in. After the reaction had finished, the product was collected and worked up in the customary manner, giving 2,3-difluoro-4-ethoxy-α-phenylbenzyl alcohol. The conversion based on the starting compound was 97%.
