To a stirred solution of HATU (630 mg, 1.66 mmol) in DMF (1 ml) was added ethyldiisopropylamine (570 μl, 3.3 mmol), followed by 5-methyl-[1,3,4]oxadiazol carboxylic acid potassium salt (138 mg, 830 μmol) and stirred for 20 min. Then (1S,2R)-1-{[1-(4-fluorophenyl)-1H-indazol-5-yl]oxy}-1-phenylpropan-2-amine (300 mg, 830 mmol) in DMF (1 ml) was added to the brown/red solution and the stirring was continued for 24 h at r.t. The mixture was diluted by dichloromethane and filtrated through a path of silica gel. Solvent was removed under reduced pressure, and the residue was purified by preparative TLC on silica gel (hexane/acetone 50%). Yield 82 mg (21%).
