Abstract
Disclosed are three-component crystals comprising compounds of Formula II, compounds of Formula III and an amine base in an equimolar ratio (1:1:1). Also disclosed are methods for preparing the three-component crystals comprising compounds of Formula II, compounds of Formula III and an amine base in an equimolar ratio (1:1:1). Further disclosed are methods for the preparation of chlorantraniliprole using the three-component crystals of the disclosure.
Claims7
A solid three-component crystal, wherein the three components are:
- (a) a compound of Formula II:
- (b) a compound of Formula III;
- and
- (c) an amine base,
- wherein the components are in an equimolar ratio of 1:1:1.
A method for the preparation of a solid three-component crystal, wherein the three components are:
- (a) a compound of Formula II:
- (b) a compound of Formula III;
- and
- (c) an amine base,
- the method comprising the steps of:
- (i) forming an admixture of the compound of Formula II, the compound of Formula III and the amine base in an equimolar amount of 1:1:1 in an aprotic solvent,
- (ii) forming the three-component crystals therefrom, and
- (iii) isolating the three-component crystals from the polar aprotic solvent.
