実験手順

To a solution of 2,5-dimethoxyphenylacetic acid (1 mmol) and Et3N (1 mmol) in CH2Cl2 was added p-toluenesulfonyl chloride (1 mmol) at rt. After 1 h, the mixture was treated with a solution of the product of step 1, 6-chloro-5-amino-4-butyl pyrimidine (1 mmol in CH2Cl2), followed by addition of Et3N (2 mmol). The resultant mixture was refluxed for 20 h. Solvent was removed and the residue dissolved into EtOAc, the organic layer washed with water and dried. The crude compound was taken into acetone, and precipitated product filtered out and washed with a small amount of acetone to give N-(4-butylamino-6-chloro-pyrimidin-5-yl)-2-(2,5-dimethoxyphenyl) acetamide. Rf=0.45 in 1:1 EtOAc:hexane. 1H NMR (DMSO-d6) δ 9.37 (s, 1H), 8.17 (s, 1H), 7.11 (t, 1H), 6.9 (d, 1H), 6.88 (d, 1H), 6.78 (dd, 1H), 3.73 (s, 3H), 3.69 (s, 3H), 3.63 (s, 3H), 3.35 (m, 2H), 1.48 (m, 2H), 1.29 (m, 2H), 0.88 (t, 3H).
