実験手順

179 mg of nojirimycin is dissolved in 20 ml of water, followed by adding 1 ml of formalin, adding 100 mg of platinum on carbon catalyst and carrying out a catalytic reduction at ordinary temperature and under atmospheric pressure. The following treatments are carried out in the same manner as in Example 2 to obtain 150 mg (85%) of N-methyl moranoline.
