Versuchsvorschrift

To a solution of N2-(tert-butoxycarbonyl)-N2-methyl-N-[3-(triphenylphosphonio)propyl]glycinamide chloride (7.6 g, 14 mol) in methylene chloride (38 mL) and methanol (4.2 mL) was added 2.0 M HCl in diethyl ether (16 mL, 32 mmol), and the mixture was stirred overnight at room temperature. The solution was cooled to 0° C. and treated with 7 M ammonia in methanol (6.0 mL, 42 mmol), giving an immediate white precipitate. After 30 minutes, the slurry was filtered and the flask and filter cake were rinsed with methylene chloride (68 mL). The filtrate was concentrated to give the title compound (6.2 g, 100%) as a crude white solid.
