8-(1-iododibenzo[b,d]thiophen-4-yl)-2-morpholino-4H-chromen-4-one (20 mg, 0.04 mmol), 1-ethylpiperazine (9.42 µl, 0.07 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (2.145 mg, 3.71 µmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM (0.849 mg, 0.93 µmol) and 2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepine (16.62 µl, 0.11 mmol) were suspended in dioxane (250 µl) and sealed into a microwave tube. The reaction was degased, purged with argon and heated to 130 °C over a period of 45 minutes in the microwave reactor. No reaction.
