Acetic Acid → alpha-[4-(Benzyloxy)-3-methoxyphenyl]-4-quinolinemethanol

Participants

Reaction Steps

25 ml of tert.-butylithium solution (1.4M in hexane) are added dropwise at -70° within 10 minutes to 10 g of 4-benzyloxy)-3-methoxy-bromobenzene dissolved in 100 ml of tetrahydrofuran. After stirring at -70° for 1 hour, 5 g of quinoline-4-carbaldehyde dissolved in 50 ml of tetrahydrofuran are added dropwise within 30 minutes. The reaction mixture is stirred at -40° for 1 hour and at -5° for 1 hour, poured into 200 ml of water and adjusted to pH 4 with glacial acetic acid. The mixture is extracted three times with 50 ml of ether each time. The combined ether phases are washed with water, dried over sodium sulfate and evaporated. There is obtained α-[4(benzyloxy)-3-methoxyphenyl]-4-quinolinemethanol as an amorphous solid.
