The alkylation of N-acetyl-L-cysteine (I) with dodecyl bromide (II) by means of ammonia in methanol gives N-acetyl-S-dodecyl-L-cysteine (III), which is treated with isobutyl chloroformate and N-methylmorpholine (NMM) in THF yielding the mixed anhydride (IV). The reaction of (IV) with diazomethane in ethyl ether affords the diazoketone (V), which is finally treated with HCl in ethyl acetate.
