1 – (3 ‘, 4’-methylene-dioxy-phenyl) -2 – pyrrolidin-1 – pentanone hydrochloride Synthesis

1 – (3 ‘, 4’-Methylenedioxyphenyl)-2-pyrrolidino-1-pentanone hydrochloride as a authentic white to light-brown, decidedly hydrophilic breakable crumb with a slight odour The minimum abstention is 99.5%. It acts as a stimulant.

1 – (3,4 – methylene dioxyphenyl) -2 – pyrrolidin-1 – pentanone hydrochloride as an antidepressant, has a top ability and continued duration, etc.. The commodity 1,2 – methylenedioxybenzene as a starting material, by Friedel-Crafts acylation reaction, a carbonyl accumulation of the bromination acknowledgment of the α-H, a halogenated hydrocarbon with pyrrolidine in the nucleophilic barter reaction, and again acidification action a absolute crop of 74.3% Preparation of 1 – (3,4 – methylene-dioxy-phenyl) -2 – pyrrolidin-1 – pentanone hydrochloride. N-pentyl chloride as the acylating agent, in altered agitator catalyzed 1,2 – methylenedioxybenzene and Friedel-Crafts acylation reaction. The beginning after-effects showed that the metal oxide catalytic selectivity characteristics beneath than the catalytic backdrop of metal chlorine compounds. With dichloromethane as the acknowledgment solvent, 1,2 – (methylenedioxy) benzene, n-pentyl chloride, the admeasurement of the bulk of adamant chloride is 1:1.15:1.1, acknowledgment at a temperature beneath 5 ℃ for 5 h, 1,2 – methylenedioxybenzene about-face amount of added than 99%, the product, 1 – (3,4 – methylene-dioxyphenyl) -1 – pentanone selectivity of 88.0%.
