All interatomic distances in the title compound, C~13~H~15~N~3~O~2~S, are normal. The 1,2,4-triazole ring is planar and is inclined at 46.50 (6)° to the phenyl ring. The ethoxycarbonylmethyl group is also close to being planar and is inclined at 87.54 (9)° to the 1,2,4-triazole ring. The crystal was
