Described is the in situ preparation of the hemiacetals of α-alkoxyacetaldehydes. The hemiacetals are generated by hydrolysis of an acetal precursor in aqueous acetonitrile solutions. These hemiacetals serve as stable aldehyde equivalents, thus circumventing the production and isolation of unstable α-alkoxyaldehydes. The hemiacetal of 2-methoxyethoxyacetaldehyde is utilized in an effective and efficient preparation of Dirithromycin (LY237216).
