実験手順
5.0 g of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-ylamine in 7.6 ml of ethyl 2-bromoacetate are placed in a round-bottomed flask and the mixture is stirred at ambient temperature for 20 h. A precipitate forms, and is recovered by filtration, washed with diethyl ether and then with ethanol, and oven-dried under reduced pressure. 8.78 g of compound are obtained.
