実験手順

A mixture of 1-[6-(2,6-diethyl-phenyl)-4-ethoxy-pyridin-3-yl]-butan-1-ol (67 mg, 0.20 mmol), 3-ethoxy-phenol (34 mg, 0.25 mmol), triphenylphosphine (65 mg, 0.25 mmol), and DEAD (36 mg, 0.25 mmol) in THF (1 mL) is stirred at room temperature overnight. Aqueous NH4Cl solution (5 mL) and hexane (10 mL) are added to the mixture, and the organic layer is separated. The organic layer is washed with NaHCO3 solution, brine, dried over Na2SO4, and concentrated. The residue is purified by PTLC to give 2-(2,6-diethyl-phenyl)-5-[1-(3-ethoxy-phenoxy)-butyl]4-ethoxy-pyridine. 1H NMR (CDCl3) 8.55 (s, 1H), 7.27 (m, 1H), 7.07-7.14 (m, 3H), 6.73 (s, 1H), 6.43-6.49 (m, 3H), 5.57 (m, 1H), 4.13 (q, 2H), 3.95 (q, 2H), 2.56-2.37 (m, 4H), 1.85-2.05 (m, 2H), 1.40-1.60 (m, 5H), 1.37 (t, 3H), 0.96-1.08 (m, 9H).
