Sodium hydride → 1-(4-Allyl-2,4,8-trimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-2-pyridin-4-yl-propan-2-ol

Participants

Reaction Steps

4-Allyl-2,4,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (1 g, 3.9 mmol) was dissolved in DMF (10 mL) and stirred for 10 min at RT. Sodium hydride (475 mg, 11.7 mmol) was added portionwise and stirring was continued for 15 min at RT. 4-(2-Methyl-oxiranyl)-pyridine (690 mg, 5.1 mmol) diluted in DMF was added dropwise at RT and the reaction mixture was further stirred for 16 h after which it was quenched with ice water and extracted with EtOAc (3×70 mL). The combined organic layer was washed with water, dried over sodium sulfate and concentrated under reduced pressure. The residue was recrystallized in ether to obtain 700 mg of 1-(4-allyl-2,4,8-trimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-2-pyridin-4-yl-propan-2-ol.
