Water → 1-(2-(Diphenylphosphanyl)phenyl)-N,N-dimethylmethanamine

Participants

Reaction Steps

A 15.0 ml portion of N,N-dimethylbenzenemethanamine and 300 ml of ether were mixed under a nitrogen atmosphere. A 58 ml portion of 2.6M butyl lithium in hexane was added and this mixture was stirred, under nitrogen for 30 hours. A mixture of 27.0 ml of diphenylphosphine chloride in 60 ml of ether was added dropwise and the mixture was stirred overnight. Water was added, the organic layer was separated and extracted twice with dilute hydrochloric acid. The combined acid extracts were basified with 10% sodium hydroxide, then extracted twice with ether. The ether extracts were combined, dried and evaporated, giving 15.9 of 2-(diphenylphosphino)-N,N-dimethylbenzenemethanamine as an oil.
