Participants

Reaction Steps

To the suspension of L-cysteine hydrochloride monohydrate (99.24 g, 565.1 mmol) in H2O (535 mL) were added EtOH (420 mL) and benzaldehyde (83.1 mL, 818 mmol) under stirring. After a few minutes, the mixture became a thick cream, which could not be stirred. Enough H2O/EtOH (3:2) solution was added to assist in stiffing the mixture. After 2.5 hrs, the mixture was filtered and the solid was washed with H2O and hexane successively. Upon drying under high vacuum, white powder (121.19 g) was obtained, which was used in the next step without further purification.
