Reaction Steps

To a solution of (81.3) (12 mg, 0.026 mmol) and hydroxylamine hydrochloride (7.11 mg, 0.102 mmol) in MeOH (3 ml) was added 2 drops of HCl (2N) by a 1-ml syringe to reach pH about 3 and the mixture was stirred in a sealed tube at 85° C. for 3 h. The mixture was evaporated to dryness and the residue was purified by preparative acid HPLC (gradient eluent NB from 20/80 to 95/5. mobile phase A: TFA/CH3CN 0.05%; mobile phase B: TFA/H2O 0.05%). The desired fractions were collected, evaporated by BUCHI under 30 mbar at 40° C. to remove CH3CN. The remained solution was lyophilized to afford the title compound (8.1 mg, yield 65.4%).
