실험 절차

4-Allyl-2,4,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (2.5 g, 9.8 mmol) was dissolved in 18 mL of DMF and stirred for 10 min at RT. Sodium hydride (1.17 g, 29.2 mmol) was added portionwise and stiffing was continued for additional 10 min. This was followed by dropwise addition of 4-oxiranyl-pyridine (2.38 g, 19.6 mmol) as a solution in DMF. The reaction mixture was stirred at RT for 16 h, quenched with ice water and extracted with EtOAc (3×120 mL). The organic layer was washed with water, dried over sodium sulfate and concentrated under reduced pressure. The residue was recrystallized in ether to obtain 1 g of 2-(4-allyl-2,4,8-trimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-1-pyridin-4-yl-ethanol.
