実験手順

N-3-Aminophenyl-5-cyano-4-thien-2-ylpyrimidine-2-amine was prepared by heating a solution of 5-cyano-N-3-nitrophenyl-4-thien-2-ylpyrimidine-2-amine (2.77 g, 8.57 mmol) and tin(II)chloride dihydrate (7.73 g, 34.05 mmol) in ethanol (160 mL) at reflux for 18 h. On cooling the reaction was concentrated under reduced pressure and partitioned between CH2Cl2 and 2M NaOH. The organic phase was dried (MgSO4) and evaporated to give the desired material (320 mg) as a yellow solid, m.p. 221-222°. δH (d6 DMSO) 10.16 (1H, s), 8.83 (1H, s), 8.24 (1H, d, J 3.9 Hz), 7.97 (1H, d, J 5.1 Hz), 7.32 (1H, dd, J 5.0, 4.0 Hz), 6.97 (3H, bm), 6.31 (1H, m) and 5.04 (2H, bs).
