실험 절차

(1c variation 2) p-Phenetidine (1.0 eq, 0.149 mmol) and triethyamine (33 mg, 0.327 mmol) were added to a mixture of 8-bromo-6-chloroimidazo[1,2-b]pyridazine hydrochloride (40 mg, 0.149 mmol) from 1b in EtOH (1.5 mL). The mixture was heated to 90° C. and stirred for 24-48 hours. The solution was then concentrated in vacuo to give crude 6-chloro-N-(4-ethoxyphenyl)imidazo[1,2-b]pyridazin-8-amine.
