Trimethoxyacetamide (2a) can be prepared from either trimethoxyacetonitrile (3) or from methyltrimethoxyacetate (1a).Similarly triethoxyacetamide can be obtained from 1b and ammonia.The synthesis of pure 1a is described.Hydrazine hydrate reacts with 1a to form trimethoxyacetohydrazide (6).The compounds 2a and 6 are formylated by tert-butoxy-N,N,N',N'-tetramethylmethanediamine ("aminal ester") at the NH2 group to furnish the formamidine 8 and the formamidrazone 9, respectively. 8 has also been prepared by reaction of N,N-dimethylformamide dimethylacetal with 2a.Reaction of 8 with phenylhydrazine affords the tetrazine 11.CH-acidic compounds such as malonodinitrile and ethyl cyanoacetate are formylated by 8 at the CH2 groups to yield the enamines 12a,b .
