FIELD: chemical industry.
SUBSTANCE: invention relates to a method for the production of a compound of formula I, said method comprising reacting a compound of formula II with a compound of formula III according to the following reaction scheme:
, where LG is Cl, A is the anion of the protic acid, and the protic acid is HCl, m is 1, n is 1, and p is 2 such that the salt of formula II has no electrical charge, where the reaction is carried out at a temperature of from 30°C to 100°C.
EFFECT: new method has been developed for obtaining a compound of formula I capable of inhibiting SHP2 activity, with a high yield, suitable for large-scale production.
