N-carbamoyl-3-chloropropanamide

Conditions: temp:5.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 20.0 g of N,N'-trimethyleneurea are partially dissolved in 1000 ml of toluene under reflux and admixed with 20.2 g of triethylamine and then dropwise, in the course of 90 minutes, with a solution of 25.4 g of 3-chloropropionyl chloride. Subsequent stirring for 30 minutes, cooling down to 5° C., removal of undissolved matter by filtration and evaporating the filtrate in vacuo gives 24 g of chloropropionylurea of the formula ##STR70## as a beige powder. under reflux in the course of 90 minutes removal of undissolved matter by filtration evaporating the filtrate in vacuo

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

Procedure: In the same way as in Example 1, reaction of 10.0 g (50 mmols) of N,N'-bis(3-aminopropyl)piperazine with 14.3 g (106 mmols) of 3-chloropropionyl isocyanate gives 24.0 g of the 3-chloropropionylurea compound of the formula ##STR11##

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

Procedure: In the same way, reaction of 6.5 g (50 mmols) of N-(2-aminoethyl)piperazine with 14.3 g (106 mmols) of 3-chloropropionyl isocyanate gives a quantitative yield of 19.8 g of the 3-chloropropionyl urea of the formula ##STR10## Melting point: 125°-130° C.
