Versuchsvorschrift
Impure 2-(2-chloro-7-(2-hydroxyethyl)-4-morpholinothieno[3,2-d]pyrimidin-6-yl)propan-2-ol (30 mg) was dissolved in toluene (5 mL, 50 mmol). Trifluoroacetic acid (0.5 mL, 6 mmol) was added and the reaction mixture was heated at 120° C. for two h. Complete reaction was confirmed by LCMS. Diluted with water and extracted with ethyl acetate, dried over magnesium sulfate, concentrated in vacuo and was purified by silica gel chromatography (0 to 100% ethyl acetate/heptanes) on the CombiFlash® Rf system using an amine column and concentrated in vacuo to give 3-Chloro-8,8-dimethyl-1-morpholin-4-yl-5,8-dihydro-6H-7-oxa-9-thia-2,4-diaza-fluorene (10 mg, 10% yield)
