Reaction Steps

2-(1H-Benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (0.27 g; alternatively N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate may be used) is added to a solution of cyclopentanecarboxylic acid (100 mg) and ethyldiisopropylamine (0.2 mL) in N,N-dimethylformamide (10 mL). The resulting solution is stirred at ambient temperature for 15 min before (2R,6S)-10-methoxy-6,11,11-trimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-benzo[d]azocine (0.20 g) is added. After stirring the solution overnight, ethyl acetate is added and the resulting mixture is washed with aqueous Na2CO3 solution and dried (Na2SO4). After evaporation of the solvent under reduced pressure, the product is obtained as a yellow oil.
