3-Chloroaniline → 4-(3-Chloro-anilino)-6-(biphen-4-yl)-7H-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

A suspension of 220 mg (0.72 mmol) of 4-chloro-6-(biphen-4-yl)-7H-pyrrolo[2,3-d]-pyrimidine and 151 μl (1.44 mmol) of 3-chloro-aniline in 5 ml of butanol is heated at boiling overnight. Cooling, filtering and washing with a large amount of ethanol and, finally, hexane yield the title compound; 1H-NMR (200 MHz, DMSO-d6): 12.46 (sb, 1H), 9.6 (s, 1H), 8.40 (s, 1H), 8.28 (m, 1H), 7.98 (d, J=8, 2H), 7.8 (m, 5H), 7.52 and 7.38 (2t, J=8, each 2H), 7.30 (s, 1H), 7.08 (db, J=8, 1H); MS: (M)+ =397.
