Procedure

A solution of indazole (0.118 g) in DMF (8 mL) was cooled to 0° C. then sodium hydride (0.06 g) added. After 15 min, [1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-dimethyl-amine (0.395 g) was added and the reaction vessel sealed and heated at 150° C. After 1 h the reaction mixture was cooled to room temperature then diluted with water. The resulting precipitate was collected by filtration then purified by chromatography (silica, 0 to 20% of a 49:1 MeOH:NH4OH mixture in dichloromethane) to furnish 116 (0.233 g, 49%) as a white solid after trituration with ethyl acetate.
