Abstract: The present invention provides crystalline polymorphic forms of Fingolimod HCl (I) and processes for preparation thereof. The application provides processes for preparation of crystalline polymorphic forms-?, ? and ? substantially free from process related impurities. The crystalline polymorphic forms of Fingolimod HCl (I) obtained by the processes according to the present invention having an XRDP pattern as per FIGS. 1, 3 and 5, which are useful as active pharmaceutical ingredient in pharmaceutical compositions for the treatment or prevention of autoimmune related disorder including multiple sclerosis.

Abstract: The present invention relates to an improved process for the preparation of anastrozole having enhanced purity from crude anastrozole having isomeric impurity content up to less than 1%. The invention also relates to a process comprising steps of converting (3-cyanomethyl-5-methylphenyl) acetonitrile to 2-[(3-cyanodimethylmethyl)-5-methyl phenyl]- meiliyl propiononitrile (II) by C-alkylation, which is further converted into 2-[3-halomethyl-5-cyanodimethyl methyl)phenyl] methyl propiononitrile (ill) by radical bromination and further to crude anastrozole by reacting (III) with sodium salt of 1,2,4-triazole, purification of the crude anastrozole by preparing its acid addition salt, generating required final anaslrozole from the acid addition salt.
