Boric Acid → 3-Aminobenzylamine

Participants

Reaction Steps

16.6 g (0.1 mol) of m-nitrobenzaldoxime obtained in Example 2, 0.3 g of a 5% Pd-C catalyst, 6.2 g (0.1 mol) of boric acid and 50 ml of ethanol were charged into a hermetically sealed glass container and stirred vigorously while charging hydrogen. Reaction was effected at temperatures of 20° to 25° C. for 8 hours. After reaction, the resulting mixture was filtered to remove the catalyst and was subject to the same post-treatment as in Example 1. 10 g of m-aminobenzylamine of 99.9% in purity was obtained (yield 82%).
