Procedure:
Methanesulfonyl chloride (9.7 mL, 56 mmol) was added to a solution of 10.5 g (48 mmol) of 2-(2-hydroxy-1-methylpropyl)-1H-isoindole-1,3(2H)-dione (JP 01242569 A2) and 8.1 mL (58 mmol) of triethylamine and the mixture was stirred at room temperature overnight. The mixture was diluted with ether and washed with water and brine. Drying (MgSO4) and removal of solvent gave an oil which slowly solidified. Trituration with hexanes gave 11.8 g of 2-[1-methyl-2-[(methylsulfonyl)oxy]propyl]-1H-isoindole-1,3(2H)-dione as a white solid, mp 67-73° C.

Procedure:
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 by addition of 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 provide 185 mg of the desired product as a white solid, mp 230-232° C.
