実験手順
This compound was prepared by the method outlined for example 5 step 6. Thus 3-(5-iodo-pyridin-2-yloxy)-azetidine-1-carboxylic acid pyridazin-3-ylamide (example 7, step 1) (600 mg, 1.15 mmol) was reacted with 2-[3-(2-benzyloxy-ethoxy)-phenyl]-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (1.5 equiv). Crude product purified by flash chromatography on silica gel eluting with 4:1 ethyl acetate:hexane to afford title compound (214 mg, 28%) as a brown foam.
