Biopharmaceutical Studies on the Alkanol Esters of Naproxen(I) -Studies of 3 Kinds Alkanol Esters of Naproxen-

나프록센의 Alkanol 에스테르류에 관한 생물약제학적 연구 I -3종의 Alkanol 에스테르의 합성-

Three new alkanol esters of d-2-(6-methoxy-2-naphthyl)propionic acid, NAPROXEN were synthesized by esterification of sodium naproxen with chloralcohols, such as 2-chloroethanol, 3-chloro-1, 2-propanediol and $\beta$-chloroethoxyethanol in dimethylformamide. These new esters were obtained with comparably high yield and identified by elemental analysis, UV, IR and NMR techniques.
