Ethyl 1-methyl-3-(2′-fluorobenzyl-nipecotate To a solution of ethyl 1-methylnipecotate (10.0 g, 58.4 mmol) in dry tetrahydrofuran (350 ml) was added at -78 C. lithium bis(trimethylsilyl)amide (80.0 ml, 80.0 mmol) as a 1.0M solution in tetrahydrofuran and the resulting solution was allowed to stir at -78 C. for 3 hours. To this was added 2-fluorobenzylchloride (7.0 ml, 8.5 g, 59 mmol) and the resulting solution was allowed to warm to room temperature over 5 hours. Thin-layer chromatography showed reaction was not complete. More 2-fluorobenzylchloride (20 ml, 2.4 g, 17 mmol) was added to the reaction mixture and the resulting solution was allowed to stir overnight, ca. 18 hours. The tetrahydrofuran was removed by evaporation in vacuo and the orange residue was dissolved in ethyl acetate. The organic solution was extracted with 0.5N HCl (4*100 ml) and the aqueous acid extracts were combined and made basic with 10N NaOH. The aqueous was then extracted with ethyl acetate (5*100 ml) and the combined extracts were dried over MgSO4 and concentrated to yield 12.1 g (74.4%) of ethyl 1-methyl-3-(2′-fluoro)-benzyl-nipecotate as an orange oil. 1 H-NMR (CDCl3) delta: 7.22-7.15 (m, 1H), 7.10-6.95 (m, 3H), 4.14-4.05 (m, 2H), 3.01 (bd, 1H, J=10.3 Hz), 2.87 (s, 2H), 2.58 (bd, 1H, J=10.3 Hz), 2.24 (s, 3H), 2.04-1.95 (m, 3H), 1.69-1.60 (m, 2H), 1.30-1.22 (m, 1H), 1.16 (t, 3H, J=7.1 Hz).
5166-67-6, The synthetic route of 5166-67-6 has been constantly updated, and we look forward to future research findings.
