A process for the production of disubstituted propionic acid derivatives which are intermediates in the synthesis of .alpha.-arylpropionic acids such as naproxen, involves the reaction of a naphthalene derivative such as 2-methoxynaphthalene, with an alkylating agent such as an alkyl pyruvate in the presence of a catalyst, and then dehydrating and hydrogenolising, or directly hydrogenolising, or derivatising and then hydrogenolising the product thereof, to produce the desired compound.
