Intermediates used in producing benzothiazole derivatives useful for preventing and treating diseases against which the activity of inhibiting leucotriene and thromboxane production is efficacious; and a process for producing the same. The process comprises condensing a hydroquinone derivative with a pyridylcarboxaldehyde derivative without protecting the hydroxyl groups of the hydroquinone and oxidizing the formed pyridylmethylhydroquinone derivative into a pyridylmethyl-1,4-benzoquinone derivative.
