反応手順

A solution of 3-(4-fluoro-3-methylphenyl)pyrrolidin-3-ol hydrochloride (9 mg, 0.039 mmol), TBTU (15 mg, 0.047 mmol, 1.2 equ.) and N-ethyl-N-isopropylpropan-2-amine (14 μL, 0.079 mmol, 2 equ.) in DMF (0.3 mL) was added to 3-(4-methylphenyl)isoxazole-4-carboxylic acid (8 mg, 0.039 mmol) and the reaction mixture was stirred at rt for 2 h. The solvent was evaporated and the crude product was purified by RP-HPLC. After evaporation of the solvents the product was dried in vacuum to yield the title compound (12 mg). MS (ESI, pos. ion) m/z calcd for C22H21FN2O3: 380.1536, found 380.1532.
