Procedure
4-(2-Chloro-pyridin-4-ylmethyl)-phenylamine was prepared by a method analogous to that described for 4-(2-trifluoromethyl-pyridin-4-ylmethyl)-phenylamine (Intermediate 2P), starting from ethyl (4-nitrophenyl) acetate and 2-chloro-4-nitro-pyridine. 1H NMR (CHCl3-d) δ 8.23 (dd, J=5.1, 0.5 Hz, 1H), 7.11 (m, 1H), 7.01 (m, 1H), 6.95 (m, 2H), 6.65 (m, 2H), 3.83 (s, 2H).
