Reaction Steps
Essentially the technique for the appropriate intermediate of Example 22 was used, but substituting 3-(t-butoxycarbonylamino)pyridazine (293 mg, 1.5 mM) for the pyrazine analogue. The reaction was carried out by heating at 45° for 4 hour, and the chromatography was carried out with a gradient from 0% to 100% ethyl acetate in dichloromethane. Relevant fractions were combined to give the desired product (315 mg).
