3,5-Dichlorophenyl isothiocyanate → HCID 23335449, compound

Participants

Reaction Steps

A mixture of 1.61 g of ethyl thiazolidine-2-carboxylic acid ethyl ester thus obtained, 2.04 g of 3,5-dichlorophenylisothiocyanate and 20 ml of toluene was heated at 90° C. for 1 hour. Then the reaction mixture was cooled and the precipitate was separated by filtration to give 3.11 g (yield 85.1%) of 3-(3,5-dichlorophenylthiocarbamoyl)thiazolidine-2-carboxylic ethyl ester. The melting point was 170.5°-171.5° C. and the results of elementary analysis were as follows: Found (calculated in parentheses): C 42.68% (42.74%), H 3.93% (3.86%), N 7.70% (7.67%), Cl 19.32% (19.41%).
