2.95 g (11.6 mmol) of bis(2-oxo-3-oxazolidinyl)phosphinic acid chloride are added at 0° C. to a solution of 4.16 g (9.67 mmol) of (2R,4S)-2-benzyl-1-(3,5-bis-trifluoromethyl-benzoyl)-4-piperidineamine [EP 532 456 A1, Example 38 f], 1.84 g (10.6 mmol) of quinoline4-carboxylic acid and 3 ml (21.3 mmol) of triethylamine in 30 ml of methylene chloride and the ice bath is removed after 10 minutes. The reaction mixture is stirred for 4 hours at room temperature and then diluted with methylene chloride. The organic phase is extracted with aqueous 10% citric acid and with 1 N potassium carbonate solution, washed with brine, dried over magnesium sulfate and concentrated to dryness by evaporation. The crude product is chromatographed on silica gel with methylene chloride/acetone (7:3). The title compound is crystallised from methylene chloride/ether/hexane in the form of white crystals. M.p.: 187° C.; TLC: methylene chloride/acetone (7:3) Rf =0.48, FD-MS: M+ =585; [alpha]D=+9.9 (c=1, methylene chloride); analysis: calc.: C=63.59%, H=4.30%, N=7.18%, F=19.47%, found: C=63.50%, H=4.40%, N=7.16%, F=19.45%. ##STR15##
