実験手順

A solution of N2-(tert-butoxycarbonyl)-N2-methyl-N-[3-(triphenylphosphonio)propyl]glycinamide bromide (53.7 g, 93.9 mmole) in methylene chloride (450 mL) was stirred with 20 weight percent aqueous lithium chloride containing 2 weight percent tetrabutylammonium chloride (4×150 mL/g). The organic layer was concentrated to dryness give the title compound in quantitative yield.
