Methyl 2-hexenoate has a green, musty, earthy, sweet, fruity odor
with a very powerful, sharp, green-fruity flavor. May be prepared
by boiling the corresponding acid with methanol in the presence
of concentrated H2S04 in chloroform and subsequent elimination of
water from the vapors using MgS04; also from 3-chloropropionic
acid methyl ester and anhydrous sodium acetate in acetic acid.
