反応手順

To a solution of 2-(pyridin-2-ylamino)thiazole-5-carbaldehyde (410 mg, 2 mmol) in ethanol (15 mL) and DMF (5 mL) was added potassium borohydride (120 mg). The resulting mixture was stirred at RT for 1 h, quenched with 10% sulfuric acid solution and concentrated in vacuo. The residue was extracted with methanol and the methanol solution was concentrated. The crude material was diluted with water, filtered and the solid was washed with water and dried in vacuo to provide compound 9A, [2-(pyridin-2-ylamino)thiazol-5-yl]methanol (385 mg, 93%) as a solid. LC/MS; (M+H)+=208
