Reaction Steps
Pyrrolidine (10.5 g, 148 mmol), cyclohexene oxide (15 mL, 148 mmol) and water (5 mL) were refluxed under nitrogen for 7h. The cooled, orange mixture was partitioned between saturated sodium hydroxide aq (150 mL) and diethyl ether (150 mL). The aqueous layer was back-washed with diethyl ether (75 ML) and the combined diethyl ether layers were dried over sodium sulfate. The diethyl ether was removed in vacuo the residual oil was vacuum distilled (bp 51° C. at full vacuum) to give (1R,2R)/(1S,2S)-2-(Pyrrolidinyl)cyclohexan-1-ol (21.9 g, 87%). 13C NMR (50 MHz, APT, CDCl3) δ 70.47 (−), 64.82 (−), 47.44 (+), 33.15 (+), 25.11 (+), 24.23 (+), 24.00 (+), 21.12 (+).
