実験手順
Method as example 47 using (S)-4-(2-chloro-6-methyl-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yl)-3-methylmorpholine (intermediate 12) and 1-(2,3-difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3-ethylurea as starting materials. The mixture was filtered through a celite 545 pre-packed cartridge (2.5 g), washed with MeOH and the solvent removed in vacuo. The crude material was purified first by Flash Chromatography using a gradient of 0-40% DCM/MeOH, then prep. HPLC at low pH yielding the title compound (8.7 mg, 0.01 mmol, 4.2%).
