Definitions

  • This invention relates to novel processes for preparing compounds of the formula (I):
  • Indazole and azaindazole substituted compounds of formula II have been described as inhibitors of CCR1. Examples of such compounds are reported in WO 2009/134666 and WO 2010/036632. The compounds are useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of CCR1 including autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis.
  • amine intermediate VI An essential intermediate in the above described synthesis of indazole and azaindazole substituted carboxamide compounds is the amine intermediate VI.
  • the known synthesis of the amine intermediate VI involves the conversion of the cyano compound below to the corresponding amine and is done by a 2-step process involving 1) reduction with sodium borohydride/trifluoroacetic acid/zinc bromide and in-situ tert- butoxycarbonylation,
  • an ionic salt comprising: i) hydrogenating a compound of the formula (II) using a metal catalyst, preferably a Pd or Ni based catalyst, more preferably Palladium over Carbon, most preferably 10%
  • Pd/C with water even more preferably 10% Pd/C/50% water
  • hydrogen preferably hydrogen at pressures of 15-1000 psi, preferably 100-200 psi for 2-20 hours, preferably 7 hours, at 0-100 ° C, preferably 25 ° C
  • an acid solution or gas preferably concentrated aqueous hydrochloric acid
  • the reaction is performed in a solvent chosen from an alcohol solvent, ester solvents, aqueous acids, ethers and toluene or other aromatic hydrocarbons solvents, preferably methanol, ethanol, isopropanol, or acetic acid, more preferably methanol, to provide a compound of the formula (I):
  • R is hydrogen or Cl-10 alkyl, preferably Cl-5 alkyl, more preferably methyl.
  • alkyl refers to a saturated aliphatic radical containing from one to ten carbon atoms.
  • Alkyl refers to both branched and unbranched alkyl groups.
  • a hydrogenation vessel is charged with 2-(methanesulfonyl)-4-cyanopyridine (8.00 g, 43.9 mmol), 10 wt.% Pd/C (50% water) (800 mg, 0.377 mmol) and MeOH (48 mL).
  • the mixture is hydrogenated under 100 psi of hydrogen at 25 ° C for 7 hours.
  • the reaction mixture is filtered to remove the catalyst, using MeOH to rinse, and the filtrate is concentrated to a volume of 24 mL. Isopropanol (48 mL) is added, followed by concentrated hydrochloric acid (4.03 mL, 48.3 mmol, 1.1 eq).
