1-Benzoyl-6-methyl-3-methyl­sulfanyl-6,7-dihydro-1H-pyrano[4,3-c]pyrazol-4-one

The title compound, C₁₅H₁₄N₂O₃S, a potent new bioactive mol­ecule which contains pyrazole and pyrone ring systems, was synthesized by the reaction of benzohydrazide and 3-[bis­(methyl­sulfan­yl)methyl­ene]dihydro-6-methyl-3H-pyran-[2,4-dione in ethanol.

Ethopabate

In the title compound (systematic name: methyl 4-acetamido-2-ethoxy­benzoate), C₁₂H₁₅O₄N, inter­molecular N—H...O and C—H...O hydrogen bonds stabilize the crystal packing. An intra­molecular C—H...O hydrogen bond generates an S(6) motif.
