Methoxy succinyl cyanide (LXV) was prepared by acylation of cuprous cyanide with methoxy succinyl chloride (XIV). Reduction of the acyl cyanide (XIV) by means of zinc dust in the presence of Ac2O produced the acetylamino ketone (LXVI). Subsequent hydrolysis of (LXVI) in aqueous HCl afforded the target aminoacid.
