N-{6-[2-(4-Fluorophenyl)chroman-6-yloxy]pyridin-3-yl}methane sulfonamide was prepared as described for N-[6-(2-phenylchroman-6-yloxy)pyridin-3-yl] methane sulfonamide in Example 46 starting from 442 mg of 6-[2-(4-fluorophenyl)-chroman-6-yloxy]-pyridin-3-ylamine (Example 76). The product was passed through silica gel using ethyl acetate-heptane (10:3) as an eluant and then crystallised from diethyl ether. 1H NMR (400 MHz, CDCl3) δ: 8.09 (d, 1H, J 2.8 Hz), 7.72 (dd, 1H, J 8.9, 2.8 Hz), 7.40 (m, 2H), 7.08 (m, 2H), 6.92-6.87 (m, 4H), 6.74 (s, 1H), 5.03 (dd, 1H, J 10.4, 2.3 Hz), 3.01 (m, 1H), 3.00 (s, 3H), 2.80 (m, 1H), 2.19 (m, 1H), 2.07 (m, 1H).
