5-Meth­yl-2-methyl­sulfan­yl-7-phenyl­pyrazolo[1,5-a]pyrimidine-3-carbonitrile

The pyrazolo[1,5-a]pyrimidine ring system of the title compound, C₁₅H₁₂N₄S, is essentially planar and the dihedral angle between the plane of the pyrazolo[1,5-a]pyrimidine system and the plane of the phen­yl ring is 134.6 (7)°.

4-{2-[2-(4-Formyl-2-methoxy­phen­oxy)eth­oxy]eth­oxy}-3-methoxy­benzaldehyde

The title compound, C₂₀H₂₂O₇, was prepared by reaction of 4-hydr­oxy-3-methoxy­benzaldehyde and 1-chloro-2-(2-chloro­ethoxy)ethane. Inter­molecular C—H...O hydrogen-bonding contributes to the stability of the structure in the solid state.
