Reaction Steps

Method as described for example 147 using 1-(2-chloro-4-morpholino-5H-pyrrolo[3,4-d]pyrimidin-6(7H)-yl)ethanone (intermediate 23) and 1-ethyl-3-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl) (intermediate 28) as starting materials. The crude reaction mixture was purified by SCX-2 cartridge (loaded in MeOH eluted with 2M methanolic ammonia). Ammonia eluent was concentrated in vacuo. Residue was then purified by prep. HPLC at high pH to afford an off white solid (17.4 mg, 0.04 mmol, 8%).
