A solution of 3-(4-methoxyphenyl)-isoxazole-4-carboxylic acid (7 mg, 0.03 mmol), N-ethyl-N-isopropylpropan-2-amine (16 μL, 0.09 mmol, 3 equ.) and TBTU (12 mg, 0.036 mmol, 1.2 equ.) in DMF (0.3 mL) was added to 2-[(3R)-piperidin-3-yl]propan-2-ol hydrochloride (5 mg, 0.03 mmol). After 1 h at rt the crude product was purified by RP-HPLC. The pure fractions were basified (NaHCO3) and extracted with ethyl acetate, dried (Na2SO4), evaporated and dried in vacuum to yield the title compound (8 mg). MS (ESI, pos. ion) m/z: calcd for C19H24N2O4: 344.1736, found 344.1737.
