Reaction Steps

To a microwave vial were added N-((4S,6S)-4-(2-fluoro-5-hydroxyphenyl)-4-(fluoromethyl)-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-2-yl)benzamide (95 mg, 0.229 mmol), 2-fluoro-pyrazine (24.74 mg, 0.252 mmol), cesium carbonate (90 mg, 0.275 mmol) in DMSO (459 μL). The vial was heated in microwave instrument at 100° C. for 30 min. After cooling to room temperature, water was added to the reaction mixture and precipitate was observed. After stirring for 10 min, the precipitate was collected by filtration, washed with water and hexane, dried in vacuum oven at 60° C. for 1 h to provide N-((4S,6S)-4-(2-fluoro-5-(pyrazin-2-yloxy)phenyl)-4-(fluoromethyl)-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-2-yl)benzamide (85 mg, 0.173 mmol, 75% yield) as off-white solid. MS m/z=493 [M]+. Calculated for C23H17F5N4O3: 492.4.
