Versuchsvorschrift

A microwave vial was charged with N-(3-((4S,6S)-2-benzamido-4-(fluoromethyl)-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-4-yl)-4-fluorophenyl)-5-methoxypyrazine-2-carboxamide (0.11 g, 0.200 mmol, step 1). MeOH (2 ml) was added followed by 1,8-diazabicyclo[5.4.0]undec-7-ene (0.122 g, 0.801 mmol, Aldrich). The vial was sealed and heated to 75° C. in a microwave (Biotage Initiator) for 1.5 hours. The reaction was cooled to RT and concentrated under reduced pressure. The crude material was purified via silica gel flash chromatography using a gradient of 5-70% EtOAc in hexanes to afford the title compound as a white solid (0.0741 g, 0.166 mmol, 83% yield). MS m/z=446.0 [M+H]+. Calculated for C18H16F5N5O3: 445.343
