実験手順
Methyl 3-hydroxy-6-isopropylthieno[2,3-b]pyridine-2-carboxylate (1.6 g) and 5-amino-2-neopentyloxybenzonitrile (2.6 g) were stirred at 170° C. for 2 hr. Then the reaction mixture was treated with diluted hydrochloric acid and the organic layer was extracted with ethyl acetate. The extract was washed with brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained crystals were recrystallized from water-containing dimethylformamide to give the title compound (0.6 g). melting point: 211-212° C.
