実験手順
A solution of 4-[(3-amino-6-thiophen-2-yl-pyrazin-2-ylamino)-methyl]-phenol trifluoroacetic acid salt (10 mg, 0.024 mmol) in triethyl orthoformate (1.5 mL) was refluxed for 4 hours. The starting material was disappeared completely. After evaporation of triethyl orthoformate, the crude product was crystallized in hexane-dichloromethane system to provide 4-(6-thiophen-2-yl-imidazo[4,5-b]pyrazin-1-ylmethyl)-phenol as a brown solid (5 mg).
