Patent ID: 8367868

Claim:
Process for the synthesis of compounds of formula I where: A is phenyl, benzyl, tolyl or thiophenyl, Y is phenyl, tolyl, trihalomethyltolyl, alkoxytolyl or naphtyl, comprising the following stages: a) halogenating an amino alcohol of formula II: where A has the foregoing meanings, in order to obtain the salified amino halogen-derivative of formula III: where X represents a halogen; b) protecting the amino group of the salified amino halogen-derivative of formula III with a protective agent of the amino groups, in order to obtain the compound of formula IV where A and X have the foregoing meanings and G indicates a protector group of the amino groups having formula R—C(═O)—, where R is an alkyl residue, aryl residue or alkoxy residue, or having formula R′—S(═O) 2 —, where R′ indicates an alkyl residue or aryl residue; c) performing a substitution reaction on the protected amino halogen-derivative of formula IV by the anion of an aryl alcohol of formula Y—OH, where Y has the foregoing meanings, to give the protected aryloxypropylamine or heteroaryloxypropylamine of formula V; and d) deprotecting the amino group.
