3-methyl-1,1-dipropylurea

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: 1 mol of N-methyl dipropylurea and 1 mol of formol in aqueous 30% solution are mixed. To this solution 1 mol of morpholine is slowly added while cooling. The stirring is maintained one hour after the end of the N-methyl dipropylurea addition. After evaporation to dryness a crystalline product is obtained which melts at 110°C. The yield of the reaction is 98%. while cooling The stirring is maintained one hour After evaporation to dryness a crystalline product is obtained which melts at 110°C

Conditions: temp:137.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a 250 ml, 3-neck flask, with an agitator and condenser were added 22.0 g (0.25 mol) of 1,3-dimethylurea, 25.3 g (0.25 mol) of dipropylamine and 100 ml of cumene. The solution was heated at reflux (about 137° C.) for about 12 hours, cooled to 100° C., and the solvent was removed using vacuum distillation to provide a residue. The residue was dried in a vacuum oven at 60° C. to provide 41.5 g of 1,1-dipropyl-3-methylurea. The solution was heated cooled to 100° C. the solvent was removed vacuum distillation to provide a residue The residue was dried in a vacuum oven at 60° C.
