Procedure
To a microwave vial is added N-((1S)-1-((1R)-2-(((4S)-8-bromo-6-(2,2-dimethylpropyl)-3,4-dihydrospiro[chromene-2,1′-cyclobutan]-4-yl)amino)-1-hydroxyethyl)-3-buten-1-yl)-2-methoxyacetamide (100 mg, 191 μmol), cesium carbonate (311 mg, 955 μmol), 1H-imidazole (65 mg, 955 μmol), and copper(I) iodide (36 mg, 191 μmol). The vial was purged with N2 5×, then 10:1 DMF/H2O (2 mL) and N1,N2-dimethylethane-1,2-diamine (21 μl, 191 μmol) were added. The vial was sealed and heated in a microwave at 185° C. for 30 min. The crude product was dissolved in DMF, filtered through an Acrodisc filter and purified by reverse phase HPLC to afford the title compound as a white amorphous solid. MS m/z=511.4 [M+H]+.
