Abstract
In the title compound, C18H13ClN2OS·CH3OH, the dihedral angle between the benzimidazole group and the naphthyloxy moiety [82.89 (5)°] very near to orthogonality. The H atom in the five-membered ring is disordered with equal occupancies at the two N atoms and the H atom of the methanolic hydroxy group is disordered with equal occupancies over two sites at the O atom. The methanol molecule acts as a hydrogen-bond acceptor for the amino H atom and donates a hydrogen bond to the nonprotonated ring N atom. As a result, chains are formed running along the a axis.
