1-(4-chlorophenyl)-3-methylthiourea

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

Procedure: Obtained (a) by a procedure analogous to that indicated in Example 1(a), from 3'-diethylsulfamoyl-2-bromo-4'-chloroacetophenone and 1-(4-chlorophenyl)-3-methylthiourea, or (b) by a procedure analogous to that of Example 1(b), by boiling 4-(3-diethylsulfamoyl-4-chlorophenyl)-2-(4-chlorophenyl-imino)-3-methylthiazolidin-4-ol hydrobromide for 2 hours in glacial acetic acid and filtering off the crystals after cooling. Melting point 207° C. (with decomposition). for 2 hours filtering off the crystals after cooling

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