Reaction Steps

Palladium on BaSO4 (5%, 0.4 g) was added to a degassed solution of the benzyl hydroxamate 20 (0.9 g) in MeOH (75 mL) and the suspension was treated with hydrogen at atmospheric pressure for 6 h. The suspension was filtered over a Celite® bed and concentrated to yield the desired hydroxamate 21 (˜0.8 g, quantitative yield). 1H NMR (400 MHz, DMSO-d6): 10.38 (s, 1H), 8.72 (s, 1H), 7.24 (d, J=8.0 Hz, 2H), 7.16 (d, J=8.8 Hz, 2H), 6.88 (d, J=7.6 Hz, 2H), 6.83 (d, J=8.4 Hz, 2H), 4.58 (m, 1H) 3.10-3.45 (m, 8H), 2.76-2.85 (m, 4H), 2.24 (t, J=7.2 Hz, 2H), 2.00 (s, 3H), 1.32 (s, 9H).
