The syntheses of a number of 1-substituted 5-aminoimidazole-4-carbaldehydes 3, by the reduction of the corresponding 5-amino-4-cyanoimidazole derivatives is reported using LiAlH(OEt)3, prepared in situ from LiAlH4 and ethyl acetate. The compounds of type 1 are useful intermediates for the synthesis of elongated adenine derivatives.
