Procedure
Morpholine was added to a suspension of 12-bromo-5H-6-thia-4,5-diaza-chrysene 6,6-dioxide 545 (100 mg, 0.28 mmol), Hermann's palladacycle (13 mg, 14 μmol), Mo(CO)6 (73 mg, 0.28 mmol), DBU (126 mg, 0.83 mmol) and THF (2 ml) in a microwave vessel. The vessel was sealed under air and the mixture was heated in the microwave at 150° C. for 15 min. After cooling, the mixture was concentrated in vacuo. The residue was diluted with MeOH (2 ml), filtered and the filtrate was purified by preparative HPLC (acidic conditions 1) to give the title compound (6 mg, 6%).
