Procedure

To a solution of 2-{2-[(benzyloxy-formyl-amino)-methyl]-3-oxo-2,3-dihydro-benzo[1,4]thiazin-4-yl}-N-propyl-acetamide (0.13 mmol) in 9 ml of EtOH is added Pd/C (10%) (65.6 mg) followed by 1,4-cyclohexadiene (1.29 mL). The reaction mixture is stirred at room temperature for 12 hours and the final product 2-{2-[(formyl-hydroxy-amino)-methyl]-3-oxo-2,3-dihydro-benzo[1,4]thiazin-4-yl}-N-propyl-acetamide is obtained by preparative LC/MS using 1 to 99% ACN (in the absence of TFA) as gradient. MS: (ES+): 338.2 [M+1].
