The title structure crystallizes in a triclinic unit cell as an ion pair with a single disordered solvent mol­ecule. Hydrogen bonding is observed between the carb­oxy­lic acid moiety and the tetra­hydro­furan solvent.

The title mol­ecule exists in a thio­ketone form, in which weak intra­molecular N—H⋯O and C—H⋯O hydrogen bonds are observed. In the crystal, inter­molecular N—H⋯S and N—H⋯O hydrogen bonds, and π–π inter­actions link the mol­ecules, forming a three-dimensional network.

The crystal structure of the fumarate salt of the synthetic psychedelic 4-HO-DPT is reported as its tetra­hydrate. A series of N—H⋯O and O—H⋯O hydrogen bonds connect the ions and water mol­ecules of crystallization into a three-dimensional network.

In the title compound, the dihedral angle between the pyridine and benzene rings is 55.68 (11)°. In the crystal, N—H⋯N hydrogen bonds link the mol­ecules into [010] chains.
