Reaction Steps

To a solution of 58 (1 g, crude) in MeOH (5 mL) was added MeOH—NH3 (5 mL) at 0° C. and stirred at rt for overnight. The reaction mixture was evaporated to obtain the desired compound (600 mg, crude) as a brown liquid. Rf: 0.2 (10% MeOH/CHCl3). The crude compound was used in the next step without further purification; (m/z): 199, 201 [MH]+.
