実験手順

100.0 mg (0.325 mmol) of 2-[3-(4-chlorophenyl)-4-cyclopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-propionic acid from Example 105A are placed in 2 ml of DMF and treated with 61.2 mg (0.357 mmol) of (1S)-1-(1-naphthyl)ethanamine, 52.7 mg (0.390 mmol) of HOBt and 81.0 mg (0.422 mmol) of EDC hydrochloride. The mixture is stirred overnight at room temperature, then partitioned between dichloromethane and water, and the organic is phase separated, dried over sodium sulphate and concentrated. The residue is purified by flash chromato-graphy on silica gel (eluent: first dichloromethane, then dichloromethane/methanol 100:1) and then further separated by preparative HPLC on chiral phase [Method 15]. 51 mg (34% of theory) of the diastereomerically pure target compound are thus obtained (see also Example 186).
