PROCEDURE

实验过程

4-Chloro-5-methyl-thieno[2,3-d]pyrimidine-6-carboxylic acid methyl ester (1.17 g), (S)-tert-butyl 3-(2-amino-5-fluorophenoxy)piperidine-1-carboxylate (Intermediate 1.1 g) was dissolved in dioxane (10 ml) and p-toluenesulfonic acid (61 mg) was added. The reaction was heated at 70° C. for 1.5 h. The solution was poured into sat. NaHCO3 (50 ml) and extracted with chloroform. The organic phases were passed through a phase separator and concentrated in vaco. The sample was purified by chromatography (silica gel; solvent: isohexan:EtOAc 3:1→2:1) to give the desired product.
