Reaction Steps
A solution of 1-(5-Fluoro-2-methoxy-3-methylphenyl)ethanamine (0.34 g, 1.87 mmol), 2,4-difluoro-1-methanesulfonyl-benzene (0.3 g, 1.56 mmol) and diisopropylethylamine (1.4 mL, 7.81 mmol) in N,N-dimethylformamide (10 mL) was stirred at 110° C. for 18 h. Dichloromethane was added (20 mL) and washed with water (2×20 mL), brine (20 mL), dried, and concentrated under reduced pressure to the crude compound which was purified by silica gel column (20% ethyl acetate in hexanes) to afford 5-fluoro-N-(1-(5-fluoro-2-methoxy-3-methylphenyl)ethyl)-2-(methylsulfonyl)benzenamine (83 mg, 14%): 1H NMR (400 MHz, CDCl3): δ 7.78 (dd, 1H), 7.07 (dd, 1H), 7.03 (dd, 1H), 6.53 (dd, 1H), 6.32 (dd, 1H), 4.82 (bs, 1H), 4.45 (m, 1H), 3.75 (s 3H), 3.07 (s, 3H), 2.41 (s, 3H), 1.48 (d, 3H).
