2,4,5-trichlorobenzenethiol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 4-acetoxybenzoyl chloride (8.37 g) in dry acetonitrile (20 ml) was added to a solution of 2,4,5-trichlorothiophenol (9.00 g) in dry acetonitrile (120 ml) and the mixture stirred at room temperature whilst pyridine (3.41 ml) was added dropwise over 10 minutes. Stirring was continued until the reaction was complete, when ethyl acetate was added and the solution washed with water. Evaporation of the solution, which had been dried over magnesium sulphate, afforded the desired thioester (15.36 g). was added dropwise over 10 minutes the solution washed with water Evaporation of the solution, which had been dried over magnesium sulphate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Prepared analogous to Example 122 from 6-(4-bromo-butoxy)-3,4-dihydro-carbostyril (m.p.: 142°-147° C.) and 2,4,5-trichloro-thiophenol.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
