참여 물질

반응 단계

A solution of 1-benzyl-3-methylpyrrolidin-3-ol (5.94 g, 31.1 mmol) in MeCN (200 mL) was cooled in an ice bath and conc H2SO4 (25 mL) was added dropwise over 15 min. The ice bath was allowed to melt and the mixture was stirred at rt over the weekend. The mixture was poured onto crushed ice (600 mL). The mixture was evaporated under reduced pressure to remove MeCN. Solid K2CO3 was added in portions to the residue until it was basic. The mixture was extracted with CH2Cl2 (3×150 mL). The combined organic extracts were washed with brine (50 mL), dried over Na2SO4 and concentrated to leave N-(1-benzyl-3-methylpyrrolidin-3-yl)acetamide (4.01 g).
