Procedure
(R)-1-(5′-Chloro-2′-methoxy-biphenyl-4-yl)-ethylamine was prepared in a similar manner to (R)-1-[4-(5-chloro-2-methoxypyridin-3-yl)-phenyl]ethylamine (Example 39) starting from (R)-[1-(4-bromophenyl)-ethyl]-carbamic acid and 5-chloro-2-methoxyphenylboronic acid. The title compound was prepared in a similar manner to (R)-1-Methyl-3-trifluoromethyl-1H-pyrazole-4-sulfonic acid 1-{[4-(5-chloro-2-methoxypyridin-3-yl)-phenyl]-ethyl}-amide (Example 39) using (R)-1-(5′-chloro-2′-methoxy-biphenyl-4-yl)-ethylamine and 3,4-difluorobenzenesulfonyl chloride. 1H NMR (400 MHz, CDCl3): 7.52-7.42 (m, 2H), 7.35-7.08 (m, 7H), 6.90 (m, 1H), 4.80 (d, 1H), 4.60 (q, 1H), 3.79 (s, 3H), 1.51 (d, 3H) ppm.
