摘要：N,N-dibenzyl ethylenediamine, N-benzyl-2-phenylethylamine, and dibenzylamine were prepd. The salts are sparingly soluble in water, and are of value as slow-release forms of penicillanic acid 1,1-dioxide, in conjunction with sparingly soluble -lactam antibiotics in chemotherapy of bacterial infections in mammals.
