Participants

Reaction Steps

N-(2-cyclobutylethylidene)-1-phenylmethanamine (1.00 g, 5.3 mmol) was dissolved in 23 mL toluene, MgBr2.0Et2 (2.07 g, 8.0 mmol) was added and the mixture was stirred at room temperature for 15 minutes. Trimethyl(1,2,2-triethoxyvinyloxy)silane (1.83 g, 7.4 mmol) was added, and the mixture was stirred at room temperature. After 3 hours, the reaction was quenched with water (30 mL) and acidified to pH=2 with hydrochloric acid. The organic phase was washed with sat. NaHCO3, dried over Na2SO4 and the solvent was removed under vacuum to yield the crude product. Column chromatography (silica, cyclohexane:ethyl acetate 10:1) yielded 1.1 g ethyl 3-(benzylamino)-4-cyclobutyl-2,2-diethoxybutanoate.
