Participants

Reaction Steps

A solution of TBTU (0.48 g, 1.5 mmol, 1,5 eq.) in DMF (2 mL) was added to a mixture of 3-methyl-5-(2-oxo-2-phenylethyl)isoxazole-4-carboxylic acid (0.24 g, 1 mmol, 1 eq), N-ethyl-N-isopropylpropan-2-amine (0.18 mL, 1 eq) and isoindoline (0.11 mL, 1 eq) in DMF (1 mL). The resulting solution was stirred at room temperature. Chloroform (25 mL) was added and the solution was washed with water and 1 M HCl, dried (Na2SO4) and evaporated. The residue was purified by flash chromatography (SiO2 1:2 heptane/EtOAc) to afford the title compound. MS (EI) 347 (M+1)
