Procedure
A mixture of 6.0 g (0.1 mole) of urea and 9.8 g (0.11 mole) of 4-amino-1-butanol was heated at 130°-135° C. for 4 hours to form monohydroxybutylurea. Without isolation the reaction mixture was cooled to 70° C. and then 31.0 g (0.21 mole) of chloral was slowly added while the temperature was maintained below 80° C. using external cooling. The reaction mixture was vigorously stirred and heated at 80°-85° C. for 1 hour. On cooling 43 g of a viscous syrupy product was isolated.
Workup
