Reaction Steps

To a solution of 5-(3′-chloro-2-fluoro-6-methoxy-biphenyl-3-ylmethyl)-pyridin-2-ylamine (P-252) synthesized above (70 mg, 0.18 mmol) in pyridine (2 ml) was added methanesulfonyl chloride (23 mg, 0.20 mmol) at 0 C under nitrogen, and stirred at room temperature for 20 h. The reaction mixture was diluted with water, neutralized with 6N HCl, extracted with ethyl acetate, washed with water and brine, and dried over Na2SO4. After it was concentrated in vacuo, the residue was purified by a chromatography on silica gel to yield N-[5-(3′-chloro-2-fluoro-6-methoxy-biphenyl-3-ylmethyl)-pyridin-2-yl]-methanesulfonamide (P-258) (25 mg, 32%). 1H NMR (400 MHz, CDCl3) 8.15 (s, 1H), 7.58 (dd, J=8.8, 2.1 Hz, 1H), 7.38 (s, 1H), 7.34 (t, J=6.6 Hz, 3H), 7.24-7.31 (m, 2H), 7.11 (t, J=8.5 Hz, 1H), 6.73 (d, J=8.5 Hz, 1H), 3.89 (s, 2H), 3.77 (s, 3H), 3.09 (s, 3H) ppm.
