Reaction Steps

A mixture of 0.387 mmol 2-isopropoxy-5-methanesulfonyl-benzoic acid (example BI), 0.464 mmol 2,3-Dihydro-1H-isoindole (commercial), 0.426 mmol TBTU and 1.935 mmol DIPEA in 1.4 ml DMF was stirred at RT for 2 h. The reaction mixture was evaporated in vacuo. The residue was taken in water and extracted with ethylacetate. The combined organic phases were washed with saturated sodium bicarbonate solution, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by chromatography (SiO2, heptane/ethyl acetate) to yield the title compound as a light brown solid (88% yield). MS (m/e): 360.2 [M+H]+, 100%)
