Методика
17.7 g of N′-benzyloxycarbonyl-N-methyl-hydrazine carboxylic acid tert-butyl ester was dissolved in 20 mL of ethyl acetate, added with 70 mL 4N hydrogen chloride-ethyl acetate solution, and stirred at room temperature for 4 hours. The solvent was evaporated, and the resulting crystals were washed with diethyl ether and filtered, to afford 11.4 g of the title compound as white crystals.
