実験手順
A mixture of N-(trans-4-trifluoromethyl-cyclohexyl)-2-[N-methyl-N-aminocarbonylmethyl-amino]-4-methylamino-5-nitro-benzoic acid amide (compound IIIa, 45 mg, 0.104 mmol), Burgess reagent (27 mg, 0.11 mmol, +20 mg after 0.5 h, +15 mg after 2.5 h, +20 mg after 16 h), DCM (2 mL) and THF (2 mL) is stirred for 2.5 h at rt, then for 13.5 h at 40° C. and then for 2 h at reflux. The mixture is diluted with sat aq NaHCO3, extracted with EtOAc and the combined organic phases are dried with Na2SO4, filtered and concentrated and directly used in the next step. Yield: 80 mg. HPLC Rt=1.36 min (method A). MS m/z: 414 [M+H]+.
