実験手順
2-(Pyridin-4-yl-oxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (22) was prepared according to the same procedure for compound 9, except using 4-hydroxypyridine. The crude product was purified with ethyl acetate to afford 1.31 g (47%) of 22 as a colorless oil. 1H NMR (300 MHz, CDCl3) δ 8.42 (m, 2H), 6.87 (m, 2H), 4.15 (m, 3H), 3.43 (m, 2H), 1.98 (m, 4H), 1.50 (s, 9H).
