Условия реакции

Методика

The hydrochloride of 3-[N-(3-chloropropyl)methylamino]-N,N,N-trimethyl-propan-1-aminium chloride has been prepared by reacting thionyl chloride with 3-[N-(3-hydroxypropyl)methylamino]-N,N,N-trimethylpropan-1-aminium chloride hydrochloride. This 3-[N-(3-hydroxypropyl)methylamino]-N,N,N-trimethylpropan-1-aminium chloride hydrochloride has been prepared (a) by heating N,N,N-trimethyl-[3-(methylamino)]-1-propanaminium bromide with oxetane, and treating the resulting product with concentrated hydrochloric acid; and (b) by reacting 3-[N'-formyl-N'-(3-hydroxypropyl)amino]-1-propanamine hydrochloride with iodomethane in the presence of sodium carbonate to form 3-[N'-formyl-N'-(3-hydroxypropyl)amino]N,N,N-trimethyl-propan-1-aminium chloride, and reacting the latter with formalin in formic acid followed by concentrated hydrochloric acid.
