Diisopropylethylamine → 3-(1-{[5-(4-Methylphenyl)isoxazol-4-yl]carbonyl}piperidin-3-yl)pentan-3-ol

Participants

Reaction Steps

A solution of 5-(4-methylphenyl)isoxazole-4-carboxylic acid (10 mg, 0.05 mmol), TBTU (19 mg, 0.06 mmol, 1,2 equ.) and N-ethyl-N-isopropylpropan-2-amine (17 μL, 0.010 mmol, 2 equ) in DMF (0.3 mL) was added to 3-piperidin-3-ylpentan-3-ol hydrochloride (10 mg, 0.05 mmol) and the reaction mixture was left 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 (8 mg). MS (ESI, pos. ion) m/z calcd for C21H28N2O3: 356.2100, found 356.2099.
