反応手順

Ethyl 4-fluorobenzoate and pyrrolidin-3-ylmethanol were coupled following the procedure outlined in example 28 to give ethyl 4-[3-(hydroxymethyl)pyrrolidin-1-yl]benzoate. MS (ESI): 250.0 (M+H). A similar reaction sequence as outlined in example 26 was followed using the above alcohol. 1H NMR (500 MHz, DMSO) δ 12.03 (br s, 1H), 7.76 (d, 2H), 7.25 (d, 1H), 7.21 (d, 1H), 6.89 (d, 1H), 6.56 (d, 2H), 6.38 (d, 1H), 4.05-3.95 (m, 2H), 3.90 (s, 2H), 3.56 (dd, 1H), 3.49-3.42 (m, 1H), 3.38 (dd, 1H), 3.27 (dd, 1H), 2.86-2.78 (m, 1H), 2.77 (t, 2H), 2.26-2.17 (m, 1H), 2.00-1.92 (m, 1H), 1.64-1.53 (m, 2H), 0.92 (s, 9H), 0.91 (t, 3H).
