Procedure

In substantially the same manner as in Working Example 11, 4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]-3-methoxycinnamaldehyde was condensed with 2,4-oxazolidinedione. The condensate was subjected to catalytic hydrogenation to yield 5-[3-[4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]-3-methoxyphenyl]propyl]-2,4-oxazolidinedione. The product was recrystallized from chloroform-methanol-ether to give colorless prisms, m.p.173-174° C.
