Reaction Steps

The oxime from Step 3 (590 mg, 2.69 mmol) and platinum dioxide (40 mg) in AcOH (20 ml) were hydrogenated in a Parr reactor at 30 psi for 2 hours. The mixture was filtered through Celite and the filtrate was concentrated by lyophilization to give an off-white solid. The solid was dispersed in 1N NaOH and extracted with DCM. The organic extract was dried and concentrated to dryness to give a yellow oil 525 mg (95%). m/z 206 (M+H+).
