Reaction Steps
Following the general procedure of Example 4 and making non-critical variations, but substituting ethyl chloroacetate (VI) for methyl 2-bromo-4-methylpentanoate (V) and 1,2-diamino-2-methylpropane (VI) for ethylenediamine (VII) there are obtained 5,5-dimethylpiperazinone and 6,6-dimethylpiperazinone.
