Reaction Steps

1,2-Difluoro-4-methoxy-5-nitrobenzene (INTERMEDIATE 52) (1.0 g, 5.3 mmol) and 1-methyl-4-(piperidin-4-yl)piperazine (1.066 g, 5.8 mmol) were added in a 50 mL round-bottomed flask. DMSO (6 mL) was added. The reaction was stirred at 90° C. for 1 h. After it was cooled to RT, sat. NaHCO3 (20 mL) was added. After the mixture was stirred at RT for 10 min, filtration afforded the title product as an orange solid (1.7 g, 90% yield).
