N-(Benzyloxycarbonyl)isonipecotic acid (I) was activated as the acid chloride (II) employing oxalyl chloride in the presence of a catalytic amount of DMF. Addition of diazomethane to acid chloride (II) produced the intermediate diazo ketone (III) which, upon treatment with an ethereal solution of HCl, led to the chloromethyl ketone (IV).
