Abstract: The title compound, C18H22N2O3, represents a (4S,5R,6S)-stereoisomer, crystallizing as a racemate in a centrosymmetric space group. The six-membered aliphatic ring adopts a half-chair conformation, with the hydroxy- and acetyl-substituted C atoms deviating by 0.458 (2) and -0.366 (2) Å, respectively, from the plane defined by other four ring atoms. The pyrazole ring is essentially planar [r.m.s deviation = 0.004 (2) Å]. In the crystal, the molecules are linked into chains along the b axis by N-HN hydrogen bonds. The chains are linked by O-HN hydrogen bonds into layers parallel to the bc plane.
