실험 절차

Compound 14 (3.56 g, 14.6 mmol), 1,6-dibromohexane (35.3 g, 146 mmol) and K2CO3 (2 g, 14.6 mmol) were added to 50 mL CH3CN, and the solution was stirred for 48 h. The solvent was evaporated to dryness and the residue was dissolved in a minimum amount of CH2Cl2 followed by purification via silica gel chromatographed, eluting with a 2% methanolic NH3 (7 M NH3 in methanol/98% CH2Cl2 yield the desired product as a pale yellow oil (64%). 1H NMR (CDCl3) δ 7.354 (dd, 1H, Ar), 7.121 (ddd, 1H, Ar), 7.013 (d, 1H, Ar), 6.986 (t, 1H, Ar), 3.569 (s, 2H, —CH2), 3.351 (t, 2H, —CH2—), 3.145 (d, 2H, —CH2—), 2.507 (t, 2H, —CH2—), 2.399 (t, 2H, —CH2—), 1.805 (p, 2H, —CH2—),1.447 (p, 2H, —CH2—), 1.409 (s, 9H, —C(CH3)3), 1.372 (s, 9H, —C(CH3)3), 1.362 (p, 2H, —CH2—), 1.254 (p, 2H, —CH2—). Mass Spec.=485.48 (M+H)+.
