Reaction Steps

In a manner analogous to that described in Example 3C hereinabove, 3-methyl-1,3-diaminobutane, water and acetone cyanohydrin are reacted, and the reaction product recovered. When dissolved and recrystallized from acetone it is identified as 3,3,7,7-tetramethyl-1,4-diazepin-2-one. Other primary amines may be used for other substituents.
