Versuchsvorschrift

Thionyl chloride (1.5 mL, 20.7 mmol) was added neat to [(11S)-6-amino-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinolin-11-yl]methanol (280 mg, 1.03 mmol). The nearly homogeneous yellow reaction mixture was heated to 70° C. for 2 hours and turned dark red. The reaction mixture was cooled to ambient temperature and poured over ice. While maintaining the temperature at 0° C., the pH of the mixture was brought to 14 with 50% aqueous NaOH. The resulting white suspension was extracted with CHCl3. The layers were separated and the organic layer was dried over Na2SO4 and concentrated under reduced pressure to provide a tan foam. The tan foam was slurried with acetonitrile and filtered to give 185 mg of (11R)-11-(chloromethyl)-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinolin-6-amine as a white solid. Part J
