Product 1

HCID 171682226-Chloro-N-(3,4-dimethoxyphenyl)pyridine-3-carboxamide

Procedure

6-Chloro-N-(3,4-dimethoxy-phenyl)-nicotinamide was prepared from 3,4-dimethoxy aniline and 6-chloronicotinoyl chloride following a procedure similar to the one described in the synthesis of 6-chloro-N-(4-iodo-3-methyl-phenyl)-nicotinamide, above. The product was isolated after precipitation out of a small volume of CH2Cl2 with hexanes. HRMS m/z calcd for C14H13N2O3Cl [M+H]+: 293.0688. Found: 293.0687.
