実験手順
Ethyl 6-[(1-methylpyrrolidin-3-yl)oxy]pyridine-3-carboxylate was prepared from 1-methylpyrrolidin-3-ol (0.161 g, 1.59 mmol) and ethyl 6-chloronicotinate (0.269 g, 1.45 mmol) according to the method described for Intermediate 236. The crude material was purified by FCC, eluting with a gradient of 0-20% MeOH in EtOAc to afford the title compound as a colourless oil (0.089 g, 25%). 1H NMR (250 MHZ, CDCl3) δ ppm 8.82 (1H, m), 8.13 (1H, dt), 6.74 (1H, m), 5.43 (1H, m), 4.39 (2H, dq), 2.82 (3H, m), 2.40 (3H, s), 2.39 (2H, m), 2.04 (1H, m) and 1.40 (3H, dt).
