Versuchsvorschrift

Thiazolidine-2,4-dicarboxylic acid 2,4-dimethyl ester hydrochloride (0.50 g, 2.07 mmol) was subjected to acylation with acetyl chloride (0.22 ml, 3.09 mmol) in the presence of triethylamine (0.58 ml, 4.17 mmol) to give N-acetylthiazolidine-2,4-dicarboxylic acid 2,4-dimethyl ester (with the ratio of two kinds of stereoisomers of about 49:51 as confirmed by NMR) as a pale-yellow oil (0.42 g, 83.0%).
