실험 절차

To 3,6-dichloro-pyridazine-4-carboxylic acid dimethylamide (100 mg, 0.456 mmol) was added saturated ammonia in absolute ethanol (2 mL) and the mixture irradiated in a microwave reactor to 180° C. for 45 min. 1 mL of saturated ammonia in ethanol was added and irradiation continued for an additional 30 min. The sample was concentrated in vacuo, washed with saturated ammonium chloride (1×) and brine (1×). Saturated sodium bicarbonate was added to the aqueous layer and was extracted with ethyl acetate (3×). The combined organics were dried over sodium sulfate to afford 3-amino-6-chloro-pyridazine-4-carboxylic acid dimethylamide (54.9 mg, 60%). MS: m/z 389 (M+H+).
