Definitions

  • a process for the purification of dicyclohexylamine salt of montelukast including: a) providing a solution of dicyclohexylamine salt of montelukast in a combination of an alcoholic solvent and a nitrile solvent; b) cooling the solution thereby causing a solid dicyclohexylamine salt of montelukast to separate therefrom; c) isolating the separated solid.
  • the moisture present in the starting diol intermediate of Formula (II) may be removed by performing azeotropic distillation of its solution in a hydrocarbon solvent such as toluene.
  • the moisture content of the individual reactants such as the methanesulfonyl chloride, diisopropyl ethylamine and the solvents is preferably below about 0.2% w/w to ensure that the moisture content of the total reaction medium is minimized, preferably to below about 0.2% w/w.
  • Suitable alcoholic solvents which can be used for suspending montelukast dicyclohexylamine salt include, but are not limited to alcohols such as methanol, ethanol, isopropyl alcohol, n-propanol, and the like; and suitable nitrile solvents which can be used for the purpose include, but are not limited to acetonitrile, propionitrile and the like.
  • the ratio of the alcoholic solvent to the nitrile solvent which can be used for purification ranges from about 1 :3 to about 1 :5.
  • EXAMPLE 12 PREPRATION OF 2-(3-(3-[2-(7-CHLORO-QUINOLIN ⁇ -YL)-VINYL]- PHENYL ⁇ -3-HYDROXY-PROPYL)-BENZOIC ACID METHYL ESTER (FORMULA XIII):
  • reaction mass was then cooled to -10 0 C and triethylamine (47 liters) was added to the reaction mass at about -10 0 C followed by the addition of thioacetic acid (18 liters) at about O 0 C.
  • the reaction mass was maintained at about 0 0 C for about 2 hours and then the temperature was raised to 30 0 C and maintained for 20 hours.
  • water 250 liters was added and the organic layer was separated. The aqueous layer was extracted with toluene (3x150 liters). The combined organic layer was washed with water (3*125 liters). To the obtained organic layer carbon (1.25 kg) was added and maintained for about 30 minutes.
