For the development of new antinflammatory and analgesic drugs, new 5-alkylthio (or sulfonyl) methyl-5-m-methoxyphenylhydantoin-3-acetic acid derivatives(alkyl; ethyl, propyl, butyl) were prepared. The 5,5 -disubstituted hydantoins which were used as starting materials, were prepared acording to Bucherer-Berg method. The reaction of ethyl chloroacelate with these compounds gave 3-acetate and the subsequent hydrolysis with dilute sodium hydroxide resulted in hydantoin 3-acetate and the subsequent hydrolysis with dilute sodium hydroxide resulted in hydantoin 3-acetic acid derivatives. Through the same procedure of equivalent hydroxide resulted in hydantoin 3-acetic acid derivatives. Through the same procedure of equivelent hydantions or the oxidation of 5-alkylthiohydantoin ocmpounds described above, 5-alkylsulfonylme-thyl-5-m-methoxyphenylhydantoin-30acetic acid derivatives were also synthesized.
