Reaction Steps

The hydroxamate 8 (3.4 g) was dissolved in CH2Cl2 and cooled to 0-5° C. Hydrogen chloride gas was bubbled through this solution for 20 min. The bubbling was discontinued and the reaction mixture was stirred at room temperature for 1 h. The excess HCl was degassed and the CH2Cl2 was removed. The residual solid was triturated with EtOAc (2×50 mL), decanted, and dried to yield the desired compound 9 as a white amorphous solid (2.9 g, 98%). 1H NMR (DMSO-d6): 10.39 (s, 1H), 7.21 (d, J=8.4 Hz, 4H), 6.95 (d, J=8.4 Hz, 2H), 6.99 (d, J=8.4 Hz, 2H), 4.55 (m, 1H), 2.95-2.99 (m, 2H), 2.82 (s, 3H), 2.80 (t, J=8.0 Hz, 2H), 2.73 (s, 3H), 2.25 (t, J=8.0 Hz, 2H); LCMS (m/e): Obsd. 372.0, Calcd. 371.43
