Reaction Steps

54 mg (0.53 mmol) of triethylamine are added to a suspension of 42.26 mg (0.265 mmol) of 3-(aminomethyl)phenol hydrochloride in 8 ml of dichloromethane at ambient temperature, then a solution of 100 mg (0.265 mmol) of 1-[[4-(1,1-dimethylethyl)phenyl]sulfonyl]-2,3-dihydro-(2S)-1H-indole-2-carbonyl chloride in 2 ml of dichloromethane is added over 10 minutes. This is left to agitate at ambient temperature for 1 hour. The reaction medium is washed with water, dried on magnesium sulfate, the solvents are evaporated and the evaporation residue is purified by silica column chromatography eluting with the help of a toluene/ethyl acetate mixture (8/2; v/v). The expected product is obtained in the form of a white solid with a yield of 51%.
