Chloroform → 4-(4-(4-Acetyl-2,6-dimethylphenoxy)-5H-pyrrolo[3,2-d]pyrimidin-2-ylamino)benzonitrile

Temperature

160 °C

To a suspension of 4-(4-(4-acetyl-2,6-dimethylphenoxy)-5-benzyl-5H-pyrrolo[3,2-d]pyrimidin-2-ylamino)benzonitrile (65 mg, 0.13 mmol) in 1,2-dichlorobenzene (5.3 mL) was added AlCl3 (178 mg, 1.3 mmol). The reaction mixture was heated at 160° C. for 1.5 h, after which time the reaction mixture became dark and homogeneous. Upon completion of the reaction, the reaction mixture was cooled, CHCl3 was added, and the mixture was washed with NH4Cl. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel column chromatography, eluting with hexanes:ethyl acetate (3:1), to give the product as a brown solid (41 mg, 77%).
