Tridecanoyl chloride (15.08 g, 0.061 mol) was added to a mixture of α-[(hydroxyamino)iminomethyl]-N-(2,4,6-trimethoxyphenyl)-benzene acetamide (19.8 g, 0.055 mol), Hunig's base (10.6 mL, 0.061 mol), and THF (200 mL). The mixture was stirred in THF at room temperature for 2 hours, then concentrated in vacuo and dissolved in glacial acetic acid (50 mL) and refluxed for 2 hours, then concentrated in vacuo, azeotroped with toluene (2×250 mL), and columned on silica gel eluting with 35% ethyl acetate in hexanes to yield a white solid (12.1 g, 62%). %(found): C, 68.93; H, 7.96; N, 7.54.
