Versuchsvorschrift

To a solution of 2-((2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)isoindoline-1,3-dione 31 (100 mg, 0.24 mmol) in MeOH (7 mL) was added H2NNH2.H2O (24 μL, 0.48 mmol). The reaction was heated at reflux for 1 h. After cooling to room temperature the reaction was quenched with water (10 mL) and extracted with EtOAc. The combined organics were dried over Na2SO4 and concentrated in vacuo to afford (2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methanamine 27 (0.05 g, 73%). MS (Q1) 285 (M)+
