Procedure

1.6 g of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-ylamine and 2.7 g of 2-bromo-1-[1-(phenylsulphonyl)indol-6-yl]ethanone are placed in 70 ml of ethanol and the mixture is refluxed for 20 h. A precipitate forms and is recovered by filtration, washed with diethyl ether and oven-dried under reduced pressure. 2.3 g of compound are obtained.
