Method for producing 2-heteroarylpyridine compound

Abstract

The present invention provides a method for producing a compound represented by formula (3) (in formula (3), Q, R1 and R2 are the same as those in formula (1) and formula (2)) comprising chemically reacting a compound represented by formula (1) (in the formula, Q represents a substituted or unsubstituted 5- to 6-membered or 9- to 10-membered heteroaryl group, and R1 represents a C1-6 alkyl group) with a compound represented by formula (2) (in the formula, R2 represents a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, a substituted or unsubstituted C3-6 cycloalkyl group, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted 5- to 6-membered heteroaryl group, Ra represents a C1-6 alkyl group, and X− represents a halide ion) in the presence of a base, and chemically reacting a product of the above chemical reaction with an ammonia or an ammonium salt.
