N,N-dimethylpiperidin-4-amine (0.41 g) was reacted with 4-(8-(bromomethyl)-2-chloro-9-methyl-9H-purin-6-yl)morpholine (1.0 g) via General Procedure C to yield 1-((2-chloro-9-methyl-6-morpholino-9H-purin-8-yl)methyl)-N,N-dimethylpiperidin-4-amine (0.52 g) as a white solid. This intermediate was reacted with 1-(phenylsulfonyl)-1H-indol-3-ylboronic acid via General Procedure B to give intermediate N,N-dimethyl-1-((9-methyl-6-morpholino-2-(1-(phenylsulfonyl)-1H-indol-3-yl)-9H-purin-8-yl)methyl)piperidin-4-amine. The intermediate was suspended in MeOH (3 mL) whereupon 3N KOH (0.3 mL) was added and the reaction mixture was heated at 50° C. for several hours until the protecting group was removed. Reverse phase purification gave 110.
