      PATENTS
    Patent number: 8138366
    Abstract: The present invention relates to the improved process for the preparation of highly pure form of S-[1,2-(dicarbethoxy)-ethyl]O,O-dimethyl phosphorodithioate having formula (I). The compound of formula (I) has adopted name “Malathion”. The present invention also relates to the novel process of preparing intermediate O,O-dimethyldithiophosphoric acid of formula (II), which is useful in the preparation of Malathion.
    Type: Grant
    Filed: April 28, 2008
    Date of Patent: March 20, 2012
    Assignee: Suven Life Sciences Limited
    Inventors: Veera Reddy Arava, Vaishali Nadkarni, Venkateswarlu Jasti
    Patent number: 7872132
    Abstract: An improved process for the preparation of aripiprazole (1) which comprises (i) reacting 6-hydroxy-l-indanone (11) with 1,4-dihalobutane (12) in the presence of a base and a solvent at a temperature in the range of 90 to 110 deg C to form the novel intermediate 6-(4-halo butoxy)-indan-1-one (3), (ii) reacting the novel intermediate with 1-(2,3-clichlorophenyl)-piperazine (9) to get another novel intermediate 6-[4-[4-(2,3-dichlorophenyl)-l-piperazinyl]butoxy]-indan-l-one (2) and (iii) reacting the resulting novel compound with sodium azide. The invention also relates to the novel intermediates of the formulae (2) & (3) and processes for their preparation. The invention also includes intermediate compounds useful for the preparation of aripiprazole.
