Reaktionsschritte
To a solution of 2,5-hexanediol (28 mg, 0.240 mmol) in tetrahydrofuran was added an excess of potassium butoxide. The admixture was stirred, briefly, and 2-chloro-4-fluoro-benzonitrile (37 mg, 0.240 mmol) was added. The admixture was stirred at room temperature for 72 hours. Purification by reverse phase high pressure chromatography eluting with a solvent gradient (15% of 0.1% formic acid/CH3CN in 0.1% formic acid/water to 100% of 0.1% formic acid/water) provided 28.4 mg of 2-chloro-4-(4-hydroxy-1-methyl-pentyloxy)-benzonitrile. 1H NMR (CDCl3) δ 7.50 (d, 1H), 6.95 (m, 1H), 6.79 (br d, 1H), 4.43 (m, 1H), 3.79 (m, 1H), 1.89-1.40 (m, 4H), 1.30 (d, 3H), 1.17 (d, 3H); MS m/z 253.
