Reaktionsschritte

4.0 g of t-butyl-6-benzyl-8-(methoxyimino)-2,6-diazaspiro[3,4]octane-2-carboxylate was dissolved in 40 ml of methanol and thereto 4.0 g of 10% Pd-C was added. The resulting mixture was stirred for 2 hours under the pressure of hydrogen at 5° C. filtered and concentrated under the reduce pressure to give 1.3 g of the titled compound(yield: 87.9%).
