Reaction Steps

A solution of (86.2) (120 mg, 0.287 mmol) and 2-(aminooxy)ethanol (44.2 mg, 0.573 mmol) in MeOH (10 ml) was added drops of HCl (3 N) to reach pH about 5 and then stirred at rt for overnight. Solvent was evaporated and the residue was purified by preparative base HPLC (gradient eluent NB from 20/80 to 95/5. mobile phase A: NH4OH/CH3CN 0.05%; mobile phase B: NH4OH/H2O 0.05%) to afford the title compound (20 mg, yield 15%).
