Reaction Conditions

Reaction Steps

A mixture of formic acid (0.5 ml) and acetic anhydride (0.125 ml) was stirred at 0° C. for 1 hour, then a solution of (1R)-2-[(7-chloro-3,4-dihydroisoquinolin-2(1H)-yl)sulfonyl]-N-hydroxy-1-[(2R)-tetrahydrofuran-2-yl]ethanamine (80 mg, 0.22 mmol) in anhydrous THF (5 ml) was added and the resulting mixture was stirred at RT for 1 hour. The mixture was evaporated under reduced pressure. The residue was taken up with MeOH (5 ml) and heated at 55° C. for 1 hour. The reaction mixture was evaporated under reduced pressure. After purification by crystallization in EtOAc/pentane, the title compound (22) was obtained as a white powder (37 mg, 43%). HPLC, Rt: 3.0 min (purity: 94.1%). LC/MS, M+(ESI): 389.3, M−(ESI): 387.3.
