Brine was added and the aqueous layer was extracted with EtOAc 6×. The combined organic layers were dried over Na2SO4 and concentrated. The crude product was taken up in DCM, filtered through cotton wool and purified on silica (EtOAc/n-Heptane 1:9-2:8). 25.7 mg 2-(3,5-dimethylisoxazol-4-yl)-3-(4-methoxyphenyl)-1H-indole-1-carbonitrile was obtained as a yellowish solid.
