FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chromane of the formula (I): and its salts. Method involves direct reaction of 5-(4-fluorophenyl)pyridine-3-carbaldehyde of the formula (II): with 2-aminomethylchromane or its salts under reductive conditions resulting to formation of compound of the formula (I). Synthesized compound of the formula (I) is converted to one of its salts by treatment with acid. Method provides simplifying process based on decreasing amount of by-side products formed. ^ EFFECT: improved method of synthesis. ^ 8 cl, 2 dwg, 4 ex |
