✦ Synopsis
The title compound, C 15 H 15 NO 4 , was synthesized by acylation of methyl l-2-amino-3-phenylpropanoate with furan-2carbonyl chloride at room temperature. In the crystal structure, intermolecular N-HÁ Á ÁO hydrogen bonds link the molecules into extended chains parallel to the b axis.

The title compound, C 17 H 19 NO 4 S, has two independent molecules in the asymmetric unit linked by an N-HÁ Á ÁO hydrogen bond. The principal difference between them lies in the relative orientations of the two aromatic rings. These are inclined at an angle of 3.70 (3) in one molecule but at 58.41
In the title compound, C 28 H 27 N 3 O 3 , the pyrazolone ring and the N atom of the 2-amino-3-phenylpropanoate group are essentially coplanar. The compound is in an enamine-keto form and its structure is stabilized by one strong intramolecular N-HÁ Á ÁO hydrogen bond.
