摘要:
A process for preparation of the compound (I) and salts thereof is provided. The process comprises reacting an alkali cyanide and paraformaldehyde to form a slurry of glycolonitrile followed by neutralizing, mixing the neutralized slurry containing glycolonitrile with an alkali ethoxide and an cyanoacetate to obtain the alkali salt of compound (I), and neutralizing the alkali salt of compound (I) to obtain the compound (I), wherein R represents a straight or branched chain alkyl having C 1 -C 18 carbon atoms.
