실험 절차

To a mixture of N4-(4-amino-cyclohexylmethyl)-5-nitro-N2-(2-trifluoromethoxy-benzyl)-pyrimidine-2,4-diamine (100 mg, 0.23 mmol) and 3-formyl-benzoic acid methyl ester (41 mg, 0.25 mmol) in DCM (1 mL) was added sodium triacetoxyborohydride (58 mg, 0.27 mmol). The mixture was stirred at room temperature for 18 h then quenched with excess water. The mixture was diluted with DCM and the organic layer separated and dried over Na2SO4. The solvent was removed in vacuo and the residue purified by column chromatography using an ISCO combi-flash cartridge (silica gel, DCM/MeOH) to afford 3-[(4-{[5-nitro-2-(2-trifluoromethoxy-benzylamino)-pyrimidin-4-ylamino]-methyl}-cyclohexylamino)-methyl]-benzoic acid methyl ester (76 mg, 57%), m/z 589 (M+1)+.
