実験手順
2-Oxopropanethioamide (Intermediate 2, 289 mg, 2.80 mmol) and 6-bromo-5′,6′-dihydro-4′H-spiro[chromene-2,3′-pyran]-4(3H)-imine (Example 45 Step 2, 331.4 mg, 1.12 mmol) were dissolved in acetonitrile (3 mL) and heated using MW for 20 min to 120° C. The solvent was evaporated under reduced pressure. The crude product was purified by flash chromatography using a gradient of 0-50% EtOAc in heptane but co-eluted with byproducts. The not completely pure product was used as a mixture in the next step.
