실험 절차

A suspension of 6.2 g (50 mmol) o-anisidine M10, 7.5 g (55 mmiol) 1-bromobutane M17, 7.6 g (55 mmol) K2CO3 and 0.91 g (5.5 mmol) KI in 25 ml DMF was heated at 95° C. for 24 hours. DMF was evaporated and the residue was dissolved in 100 ml CHCl3 and 100 ml saturated NaCl. The organic layer was dried over Na2SO4. The solvent was evaporated to give 9.4 g crude oil. This oil was purified by a plug packed with 45 g silica gel 100 using cyclohexane as eluant, wherein 4.8 g pure product were obtained (yield: 55%).
