실험 절차

A mixture of 5-bromo-3-chloropyridazine (1.0 equiv.), morpholine (1 equiv.) and potassium carbonate (6 equiv.) in NMP (0.2 M) were heated to 110° C. for 4 hours in an oil bath. The reaction mixture was partitioned between EtOAc and water. The organic phase was dried over sodium sulfate, concentrated and purified by normal phase chromatography. The combined fractions were concentrated and dried under vacuo to give crude 4-(6-chloropyridazin-4-yl)morpholine and was used in the next step without further purification. LCMS (m/z) (M+H)=200.0, Rt=0.34 min.
