がたい。(Problems to be Solved by the Invention) However, in the method (1), the raw material thieno[3,2-C]pyridine () is obtained by converting 3-thiophenaldehyde into diethylaminoacetal and formulating the following formula (). The compound represented by is obtained and then cyclized to synthesize it. The yield of the cyclization is the Journal of the

けられない。 In addition, in method (2), a large amount of by-products such as tertiary amines are produced in the reaction of 2-(2-thienyl)-ethyl tosylate and 2-chloro-benzylamine, so it is extremely difficult to purify and separate. Requires complicated operations. In order to avoid the by-product of tertiary or higher class amines, the amine must be used in an amount of at least twice the mole of tosylate, and the yield from the amine is low. Furthermore, even with this method, the production of by-products cannot be avoided.
