Reaction Conditions:
with potassium hydroxide;methylamine in water
Steps:
1 Preparation of N-methyl Ethylenediamine of Formula 7 (R=CH3)
EXAMPLE-1 Preparation of N-methyl Ethylenediamine of Formula 7 (R=CH3) To the stirred solution of 40% w/w methylamine (836.6 gms, 10.77 mol) in water, was added 2-chloroethylamine hydrochloride (250.0 gms, 2.155 mol) at room temperature. The reaction mixture was transferred to an autoclave and heated to 100° C. temperature for 6-7 hrs. After completion of the reaction, excess methylamine gas was released and to the mixture was added with stirring solid potassium hydroxide (1.2 kg) at ambient temperature. The organic layer was separated and dried over solid potassium hydroxide (50.0 gms). The dried organic layer was decanted to get crude product which was distilled under vacuum (10-15 mm) at 38°-45° C. to get N-methyl ethylenediamine of formula 7 (69.0 gms, 43.1% yield) as a pale yellow liquid.
