Procedure

5-Ethoxycarbonyl-3-α-naphthyl-1,2,4-oxadiazole (30.9 g.) was heated under reflux in an excess of diethylamine (35.6g.) for 1.5 hr. The mixture was cooled and evaporated under reduced pressure to give a solid which was recrystallised from methanol yielding title compound (29.3 g.), m.p. 101.5°-102.5°, λmax. (EtOH) 302 nm. (ε 9,700), νmax. (CHBr3) 1662 cm.-1 (CONEt2).
