Procedure

4-[4-(2-Fluoro-4-methanesulfonyl-phenylamino)-pyrazolo[3,4-d]pyrimidin-1-yl]-piperidine-1-carboxylic acid tert-butyl ester was prepared according to General Procedure C by the reaction of 4-(4-chloro-pyrazolo[3,4-d]pyrimidin-1-yl)-piperidine-1-carboxylic acid tert-butyl ester (Intermediate 19) with 2-fluoro-4-(methylsulfonyl)aniline (available from Aldrich Chemical Company, Inc., Milwaukee, Wis., USA). 1H NMR (400 MHz, DMSO-d6) δ 1.43 (s, 9H), 1.90-2.00 (m, 4H), 2.95-3.05 (m, 2H), 3.30 (methyl sulfonyl and water peak), 4.03-4.09 (m, 2H), 4.90-4.93 (m, 1H), 7.79-7.81 (m, 1H), 7.88-7.91 (m, 1H), 8.21-8.24 (m, 1H), 8.40-8.42 (m, 2H), 10.36 (s, 1H). Mass spectrum MH+=491.
