Reaction Steps

N4 -(Hydroxycarbamoyl-methyl)-2,N4 -diisobutyl-N1,N1 -dimethyl-succinamide (1.30 g, 0.0041 mol) was dissolved in DMF (10 ml) and treated at 0° C. with NMM (0.56 g, 0.0041 mol) followed by EDC (0.95 g, 0.005 mol) and HOBt (0.67 g, 0.005 mol). The reaction mixture was allowed to stir at 0° C. for 20 minutes and then at ambient temperature for 2 hours before O-benzylhydroxylamine (0.76 g, 0.0062 mol) was added. The reaction mixture was allowed to stir at room temperature for a further 1.5 hours. The solvent was removed under reduced pressure and the resulting crude oil was taken up in ethyl acetate (100 ml). The solution was washed consecutively with saturated aqueous NaHCO3, 1M HCl and brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo to a crude oil. The crude oil was purified by flash chromatography (silica gel, gradient elution with 5% to 10% methanol in dichloromethane) to give the title compound as a white solid (0.49 g, 29%). 1H NMR: δ(CD3OD), 7.38-7.21 (5H, br m). 4.75 (2H, s), 4.11-3.65 (2H, br m), 3.25 (1H, br m), 3.17-2.97 (2H, br m), 3.07 (3H, s), 2.81 (3H, s), 2.79-2.24 (2H, br m), 1.75 (1H, br m), 1.55-1.25 (3H, br m) and 0.91-0.64 (12H, br m).
