Procedure

The butyl (5R)-3-(2,3-dihydro-3-methyl-2-oxo-6-benzothiazolyl)-2-oxo-5-oxazolidinecarboxylate (Step 2, 685 mg, 1.95 mmol) is treated with 7N ammonia in MeOH (19 mL) with vigorous stirring, and the mixture is diluted with additional MeOH (20 mL) and tetrahydrofuran (20 mL) and stirred at ambient temperature for 1 h. The resulting slurry is concentrated under reduced pressure and then triturated and filtered from acetone to give the title compound, mp 274–276° C. (dec.); MS (ESI−) for C12H11N3O4S m/z 292 (M−H)−; [α]25D−27 (c 0.98, DMSO).
