Reaction Steps

5-(2-Chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)pyridine-3-carboxylic acid (40, mg) was reacted with 1-methylpiperizine via General Procedure B to yield 5-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)pyridine-3-yl)(4-methylpiperazin-1-yl)methanone. Crude 5-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)pyridine-3-yl)(4-methylpiperazin-1-yl)methanone (48 mg) was coupled to 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole 7 via General Procedure A to yield 14.6 mg of 348.
