YieldReaction ConditionsOperation in experiment
85.3% A pre-formed solution of <strong>[13211-32-0]tert-butoxyacetic acid</strong> 1 (26.4 g, 200 mmol) and 4-methylmorpholine (20.2 g 200 mmol) in 50 ml dichloromethane was added at 0° C. to a solution of isobutyl chloroformiate (27.3 g 200 mmol) in 150 ml dichloromethane. After additional stirring at 0° C. for 30 min, N,O-dimethylhydroxylamine hydrochloride (21.5 g, 220 mmol) was added all at once followed by the drop wise addition of 4-methylmorpholine (24.3 g, 240 mmol) over ~30 min. Stirring at 0° C. was continued for 30 min and at RT for 30 min. The reaction mixture was washed with 100 ml 1 M HCl and 100 ml 10percent brine. Both aqueous layers were extracted with 100 ml dichloromethane and the combined organic layers were dried (Na2SO4) and evaporated to dryness affording 34.7 g ("99.1percent") brown oil. Vacuum distillation over a 18 cm Vigreux column yielded 29.9 g (85.3percent) Weinrebamide 2 as a colorless oil, bp. 71° C./0.5 mbar. 1H NMR (CDCl3, 400 MHz) delta 1.26 (s, 9H), 3.19 (s, 3H), 3.71 (s, 3H), 4.17 (s, 2H).
