Yield:2424-02-4 62%

Reaction Conditions:

in water at 20;

Steps:

Allyl(methyl)amine (1a) and methyl(prop-2-ynyl)amine (1b) (general procedure).

General procedure: Allyl chloride or propargyl bromide in a 4 : 1 molar ratio, respectively, was added in portions from a dropping funnel to a 40% aqueous solution of methylamine at room temperature under constant stirring. The solution was stirred at room temperature for 3-4 h and then carefully acidified with HCl. The mixture was then treated with ether to extract unreacted halide. The amine hydrochloride solution was concentrated under reduced pressure and then transferred to a Favorsky flask equipped with aLiebig condenser and a receiver cooled by ice. A highly concentrated KOH solution was slowly added through a dropping funnel to a heated reaction mixture. The fractions boiling at 40-70°C (1a) and 45-92°C (1b) were collected, dried over MgSO4, and placed into a refrigerator. A day after, the amine layer was decanted, dried over MgSO4, and distilled from a Favorsky flask.
