Versuchsvorschrift
Dess Martin Periodinane (7.8 g, 0.0186 mol) was added in one portion to the solution of (rac)-2-hydroxymethyl-2-methyl-pyrrolidine-1-carboxylic acid tert-butyl ester (2 g, 0.0093 mol) in DCM (50 mL) under an inert atmosphere. The reaction was stirred until completion (about 2 h) then quenched with saturated solution of sodium thiosulphate, extracted with DCM (3×100 mL) washed with brine (50 mL), dried over anhydrous sodium sulphate, and concentrated using a rotary evaporator to afford 1.6 g (84%) of (rac)-2-formyl-2-methyl-pyrrolidine-1-carboxylic acid tert-butyl ester as a light brown colored oil.
