Reaction Steps

To 4-fluoro-2-(methyloxy)-1-nitrobenzene (Example 22, step A) (1 g, 5.8 mmol) in 10 mL of DMSO was added, 1-(methylsulfonyl)piperazine (1.15 g, 7.02 mmol), and K2CO3 (2.42 g, 17.5 mmol). The mixture was heated to 80° C. overnight. In the morning, the mixture was poured into 100 mL of H2O, Solid precipitated and was filtered off, washed with H2O and let air dried for a few hours. After drying under high vacuum overnight, the title compound of step A was isolated as a yellow solid. (1.09 g, 3.46 mmol, 60%). MS (ESI): 316 [M+H]+.
