40% | With sodium hydride; In N,N-dimethyl-formamide; for 18h; | c. SYNTHESIS OF (R)-6-METHYL-4-((TETRAHYDROFURAN-3- YL)OXY)PICOLINONITRILE (COMPOUND 3)To a solution of (R)-tetrahydrofuran-3-ol (693 mg, 7.86 mmol, 2.0 eq) and sodium hydride (199 mg, 7.86 mmol, 2.0 eq) in DMF (20 mL) was added compound 2 (600 mg, 3.93 mmol, 1.0 eq). After 18 hours, the reaction was diluted with EtOAc and washed with water and brine twice. The organic layer was dried (MgSO4), filtered, and concentrated in vacuo. Purification by flash chromatography on silica gel afforded 325 mg (40%) of the title compound: 1H NMR (400 MHz, , DMSO-d6) delta 7.52 (d, J = 2.28 Hz, 1H), 7.18 (d, J = 2.28 Hz, 1H), 5.22-5.19 (m, 1H), 3.91-3.33 (m, 4H), 2.46 (s, 3H), 2.34-2.25 (m, 1H), 2.00-1.93 (m, 1H); ES-MS [M+1]+: 205.2. |

54.54% | With triphenylphosphine; diethylazodicarboxylate; In tetrahydrofuran; at 20℃; | To a stirred solution of <strong>[22717-55-1]methyl 4-chloro-2-hydroxybenzoate</strong> (2.0 g, 10.718 mmol, 1.05 eq) in THF (20 mL) was added (R)-tetrahydrofuran-3-ol (1.88 g, 21.437 mmol, 2.0 eq)followed by triphenylphosphine (5.62 g, 21.437 mmol, 2.0 eq) and diethylazodicarboxylate(5.04 g, 28.940 mmol, 2.7 eq). The reaction mixture was stirred at room temperature forovernight. After completion of the reaction (monitored by TLC), the reaction mixture wasdiluted with EtOAc (200 mL) and washed with water (100 mL). The organic layer was dried10 over Na2S04, filtered and evaporated under reduced pressure. The residue was purified bysilica gel column chromatography by using 0-20% ethyl acetate in hexane gradient. Thefractions containing the expected product were combined and concentrated under reducedpressure to obtain the title compound ( 1.5 g, yield: 54.54%) as a colourless liquid. 1 H NMR(300 MHz, CDCh): 8 ppm 7.76 (d, J = 8.4 Hz, lH), 6.98 (dd, J = 8.4, 1.8 Hz, lH), 6.88 (d, J15 = 1.8 Hz, lH), 5.0-4.93 (m, lH), 4.10-3.85 (m, 7H), 2.24-2.17 (m, 2H); ESI-MS: m/z 256.91(M+Ht. |
