Versuchsvorschrift

2-Amino-5-(1,4-diazabicyclo[3.2.2]nonan-4-yl)-N-(2-(isopropylamino)-2-oxoethyl)benzamide (Intermediate 7A) (70 mg, 0.20 mmol) was dissolved in ethanol (2 mL) before addition of 3-chloro-5-fluorobenzaldehyde (46.3 mg, 0.29 mmol) followed by 2 drops of acetic acid. The resulting solution was sealed in a Reactivial® and heated at 95° C. for 24 hours. Reaction mixture was then cooled to room temperature and diluted with methanol before loading directly onto a 1 g SCX cartridge. The crude material was purified by SCX and concentrated under reduced pressure. The resultant product was re-dissolved in dichloromethane (2 mL), manganese dioxide (33.8 mg, 0.39 mmol) was added and reaction stirred overnight. The sample was then washed with water (5 mL) and extracted into dichloromethane. The organics were separated using a hydrophobic frit. The solvent was removed under reduced pressure and then re-dissolved in methanol (1 mL) and purified by preparative-HPLC. Purified sample was free-based using 500 mg SCX cartridge to afford 2-(6-(1,4-Diazabicyclo[3.2.2]nonan-4-yl)-2-(3-chloro-5-fluorophenyl)-4-oxoquinazolin-3(4H)-yl)-N-isopropylacetamide (9.0 mg, 0.018 mmol) 9% yield.
