Procedure
7.93 g of 2-(4-chlorophenyl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)imidazo[1,2-a]pyridine are dissolved in 200 ml of acetone and 100 ml of water; 223 ml of 1N hydrochloric acid are added thereto, dropwise there with stirring, and the mixture is stirred at ambient temperature for 16 h. The reaction mixture is subsequently concentrated under reduced pressure. 4.78 g of compound are obtained, which compound is used as is in the following stages.
