Reaction Steps

A solution of 3-(3-chloro-4-methoxyphenyl)isoxazole-4-carboxylic acid (10 mg, 0.04 mmol), N-ethyl-N-isopropylpropan-2-amine (14 μL, 0.08 mmol, 2 equ.) and TBTU (15 mg, 0.046 mmol, 1.2 equ.) in DMF (0.3 mL) was added to 3-(4-fluoro-3-methylphenyl)pyrrolidin-3-ol hydrochloride (9 mg, 0.04 mmol). After 1 h at rt the crude product was purified by RP-HPLC, evaporated and dried in vacuum to yield the title compound (7 mg). MS (ESI, pos. ion) m/z: calcd for C22H20ClFN2O4: 430.1096, found 430.1094.
