Abstract

Abstract This invention relates to a process for preparing novel compounds of formula: ** (Formula) ** wherein R is C3-C5 alkyl or C3-C5 alkenyl and n is an integer from 1 to 3. The terms "alkyl" and "Alkenyl" includes both straight and branched chain groups. According to a preferred embodiment, n is 3 and R is 2-methyl-1-propenyl, -CH = C (CH3) 2. Such a preferred compound is gamma- (3-pyridyl) -propyl-3-methyl-2-butenoate (n = 3, R = 2-methyl-1-propenyl and the ester moiety is substituted at the 3-position on the ring pyridyl). Other compounds include the 2-pyridyl and 4-pyridyl isomers of this preferred compound, the methyl analog (n = 1, R = 2-methyl-1-propenyl, 3-position substitution on the ring) and gamma- (3-pyridyl) -propyl-isovalerate (n = 3, R = isobutyl), substitution at position 3 of the ring).
