  • Patent number: 12404245
    Abstract: The present invention provides a process for preparing (R)-6-(tert-butoxycarbonyl)-6-azaspiro[2.5]octane-5-carboxylic acid (SM1), said process comprising the step of: iv) converting a compound of formula (VII) into a compound of formula (VIII) using a Wittig reagent in a suitable solvent; v) reacting through the Makosza reaction the compound of Formula (VIII) using bromoform and a suitable base to obtain cyclopropane compound of Formula (IX); and vi) removing bromine atoms in the presence of a reducing agent and a base in an alcoholic solvent thus obtaining (SM1). The invention relates also to a process for the conversion of the compound (SM1) for preparing (R)-4-(1-(6-(4-(trifluoromethyl)benzyl)-6-azaspiro[2.5]octane-5-carboxamido)cyclopropyl) benzoic acid (IV) or a salt thereof. The salt is preferably the sodium salt, more preferably the polymorphic form A of sodium (R)-4-(1-(6-(4-(trifluoromethyl)benzyl)-6-azaspiro[2.
