Procedure

550 mg of O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU), 300 mg of 2-amino-7-oxa-bicyclo[2.2.1]heptane-2-carboxylic acid methyl ester and 410 mg of 4-methoxy-3-(2-m-tolyl-ethoxy)-benzoic acid (example 2) were stirred in 20 ml of anhydrous DMF for 15 h at room temperature. The mixture was diluted with 150 ml of EA and washed three times with 50 ml each of a saturated aqueous sodium carbonate solution and then three times with 50 ml each of a 10% aqueous sodium hydrogensulfate solution. The organic layer was dried with magnesium sulfate, evaporated to dryness and the residue purified by silica gel chromatography (HEP/EA gradient) to yield 630 mg of the title compound as a racemic mixture.
