Method for the production of formula (I) lumateperone or its acid addition salts so that the enantiomer compound with stereochemistry 6b R, 10a S is separated form the cis racemate using resolution and the formula (II) stereoisomer is alkylated with 4-halo-4'-fluoro butyrophenone (X = I, Br, CI) to produce the formula (I) lumateperone, or optionally its acid addition salt. The object of the invention also relates to the amorphous form of the morphologically uniform p -toluenesulfonic acid salt of lumateperone and to the naphthalene-2-sulfonic acid salt of lumateperone, to the 1 :2 stoichiometry salt of lumateperone formed with naphthalene-2-sulfonic acid. |
