실험 절차

Pyridine (1 ml) was added to a mixture of 4-[[4-amino-6-[(2,6-dichloro-phenyl)-methyl]-2-pyrimidinyl]amino]benzonitrile (0.00135 mol) in CH2Cl2 (19 ml). A solution of chloroethanoyl chloride (0.001375 mol) in CH2Cl2 (0.5 ml) was added dropwise on an ice bath. The mixture was stirred at room temperature for 2 hours. More chloroethanoyl chloride (0.00625 mol) in CH2Cl2 (0.5 ml) was added. The mixture stood in the refrigerator overnight. The solvent was evaporated. The residue was treated with a saturated Na2CO3 solution and the mixture was extracted with CH2Cl2. The separated organic layer was dried, filtered and concentrated. The residue was purified by flash column chromatography over silica gel (eluent: CH2Cl2/CH3OH/NH4OH 99/1/0.1). The desired fractions were collected and the solvent was evaporated, yielding 0.22 g (36.5%) of 2-chloro-N-[6-[(2,6-dichloro-phenyl)methyl]-2-[(4-cyano-phenyl)amino]-4-pyrimidinyl]acetamide (interm. 13).
