Abstract: The invention relates to phenylethyl o-methylcinnamate and a process for its preparation. Phenylethyl o-methylcinnamate is prepared by, first, alkylating ethyl acetoacetate with o-methylbenzyl chloride in the presence of a phase transfer catalyst to yield 2-(o-methylbenzyl)-acetoacetate. Thereafter the 2-(o-methylbenzyl)-acetoacetate yielded in the alkylating step is halogenated to yield ethyl 2-halo-2-(o-methylbenzyl)-acetoacetate. This is followed by degarding the ethyl 2-halo-2-(o-methylbenzyl)-acetoacetate acid. Finally the o-methylcinnamic acid obtained in the degarding step is esterified with 2-phenylethanol into phenylethyl o-methylcinnamate. A fragrance composition utilizing phenylethyl o-methylcinnamate is also disclosed.
