发明名称 Scale-up and synthesis of 1-methoxycyglohepta-1,3,5-triene
摘要 A method for preparation of 1-methoxycyclohepta-1,3,5-triene in commercial quantities, which comprises the steps of heating 7,7-dichloro-1-methoxybicyclo[4.1.0]heptane in a refluxing reaction solvent comprising a lower boiling aromatic amine, at reflux, until suitable amounts of 1-methoxycyclohepta-1,3,5-triene have been produced, and recovering the 1-methoxycyclohepta-1,3,5-triene. Suitable reaction solvents include 2-picoline, pyridine and 2,6-lutidine. The method according to the present invention results in safer temperature control in the production of 1-methoxycyclohepta-1,3,5-triene, and increased yields.
