Procedure

To a solution of 3.77 g of cis-1,2,3,4,4a,9b-hexahydro-4a-phenyl-benzofuro[3,2-c]pyridine in 100 ml of chloroform containing 1.67 g of triethylamine was added dropwise with stirring under nitrogen a solution of 1.65 g of cyclopropane carbonyl chloride in 25 ml of chloroform. The reaction mixture was stirred at room temperature for 4 hours, diluted with 100 ml of chloroform and washed with 100 ml of 2N HCl and 100 ml of 10% aqueous NaOH. The organic layer was dried over anhydrous Na2SO4 and evaporated in vacuo to afford 4.70 g (98.1%) of a glass.
