Reaction Steps

Palladium on carbon (5%, 0.3 g) was added to a degassed solution of the benzyl hydroxamate 7 (0.4 g) in MeOH (25 mL) and the suspension was treated with hydrogen at atmospheric pressure for 4 h. The suspension was filtered over a Celite® bed and concentrated to yield the desired hydroxamate 8 (0.2 g, 72%). 1H NMR (DMSO-d6): 11.20 (s, 1H), 9.02 (br, 1H), 7.75 (d, J=8.8 Hz, 2H), 7.30 (d, J=8.8 Hz, 2H), 7.11 (d, J=8.8 Hz, 1H), 6.99 (d, J=8.8 Hz, 2H), 6.96 (d, J=8.8 Hz, 2H), 4.10 (ddd, J=12.8 10.0, and 4.4 Hz, 1H), 3.03 (dd, J=13.6 and 4.4 Hz, 1H), 2.82 (dd, J=13.6 and 10.4 Hz, 1H), 1.33 (s, 9H).
