To a mixture of DCM (3 mL) and pyridine (3 mL) was added phenylmethyl (cis)-3,4-bis(hydroxymethyl)-1-pyrrolidinecarboxylate (250 mg, 0.94 mmol) followed by tosyl-chloride (540 mg, 2.8 mmol) and the resulting solution was refluxed for 4 hours. The solvents were evaporated and the residue was azeotroped once with hexane before being purified by RP-HPLC. This yielded phenylmethyl tetrahydro-1H-furo[3,4-c]pyrrole-5(3H)-carboxylate (170 mg, 73%). LCMS: (M+H)+: 248.4.
