METHOD FOR PRODUCING 2-(-5-(4-FLUOROPHENYL)-3-PYRIDYLMETHYLAMINOMETHYL)-CHROMANE

摘要

The present invention relates to a process for the preparation of 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman, the enantiomers and its salts, characterised in that 5-(4-fluorophenyl)pyridine-3-carbaldehyde is reacted directly with aminomethylchroman or its salts under reducing conditions to give 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman, and the latter is, if desired, converted into one of its physiologically acceptable salts by treatment with an acid.
