Abstract
N,N-디메틸포름아미드 디알킬 아세탈류를 N-아실-1,4-디메톡시-2-나프틸아민의 몇 가지에 반응시켰더니 어느 경우에나 동일한 생성물인 N,N-디메틸-N'-2-(1,4-디메톡시)나프틸우레아 만이 생성 되었다. 이들 반응으로부터 N,N-디메틸포름아미드 디알킬아세탈은 반응 상대화합물에 전자밀도가 낮은 원자가 있을 때는 친핵 공격으로 반응하는 디메틸아미노화 시약으로 작용한다는 사실을 발견 하였다.

Reactions of N-acyl-1,4-dimethoxy-2-naphthylamines with N,N-dimethylformamide dialkyl acetals afforded, in all cases, the same product, N,N-dimethyl-N'-2-(1,4-dimethoxy)naphthylurea. In these reactions, it was observed that N,N-dimethylformamide dialkyl acetals act as a dimethylamination agent when electron-deficient cites are present in the substrates.
