이분갑철、2-안기분병새서화아린산이을지위원료,재무용제무최화제조건하,일과법합성료N-(2-분병새서기)-α-안기련산이을지。괄의반응조건위n(분갑철)∶n(2-안기분병새서)∶n(아린산이을지)=1.2∶1∶1.2,100℃반응3h,N-(2-분병새서기)-α-안기완기련산이을지수솔위56.4%。
N-(2-Benzothiazolyl)-α-aminophosphonate was synthesized by one-pot condensation reactions of benzal dehyde,2-aminobenzothiazole and diethyl phosphite under solvent-free conditions without catalyst. The optimum re action conditions were that n(benzaldehyde) : n(2-aminobenzothiazole) : n(diethyl phosphite)= 1.2 : 1 : 1.2, reac tion time was 3 h,reaction temperature was 100 ℃ ,the yield of the product reached 56.4%.
