Reaction Steps

A 100-mL single-neck round-bottomed flask was purged with nitrogen and charged with 205b (0.75 g, 2.80 mmol), 10% palladium on carbon (50% wet, 280 mg), and methanol (30 mL). The mixture was evacuated, charged with hydrogen gas, and stirred at room temperature for 2 h. The hydrogen was then evacuated and nitrogen was charged into the flask. The catalyst was removed by filtration through a pad of CELITE® and the filtrate was concentrated under reduced pressure to afford 205c (524 mg, 79%). MS-ESI: [M+H]+ 239.1
