実験手順

The mixture of tert-butyl (3R)-3-pyrrolidinylcarbamate (500 mg), 1-(iodomethyl)-7-oxabicyclo[2.2.1]heptane (639 mg) and K2CO3 (742 mg) in DMF (5 mL) was stirred at 75° C. for 32 hours. The resultant was added H2O, extracted with AcOEt. The organic phase was washed with brine, dried over Na2SO4, filtered, and evaporated in vacuo. The residue was purified by column chromatography on silica gel to give tert-butyl [(3R)-1-(7-oxabicyclo[2.2.1]hept-1-ylmethyl)-3-pyrrolidinyl]carbamate (416 mg) as orange oil.
