2-Methyl-2-pentenal → HCID 54279173, compound

Participants

Reaction Steps

A Grignard reagent, prepared by reacting 29.4 g (1.21 g atoms) of magnesium in 200 ml of ether and 183 g (1.21 mol) of 3-bromopentane in 400 ml of ether, is reacted with 98.0 g (1.0 mol) of 2-methyl-2-pentenal in a manner analogous to Example 5. Fractional distillation of the crude product (159.3 g) over a 20 cm Widmer column gives 95.5 g (56.2%) of olfactorily good 4-methyl-6-ethyl-3-octen-5-ol of melting point 92°-93° C./12 mm Hg.
