The present invention provides crystalline forms of a compound of formula (I). Also provided are pharmaceutical compositions that include the provided crystalline forms and methods of using the provided crystalline forms and pharmaceutical compositions for the treatment of cancer. It has been discovered that crystalline forms of 4-(5-Chloro-2- isopropylaminopyridin-4-yl)-1 H-pyrrole-2-carboxylic acid [1 -(3-chlorophenyl)-2- hydroxyethyl]amide can be prepared which exhibit improved properties, e.g. surprisingly improved stability and improved solubility characteristics. Thus, the present invention provides crystalline 4-(5-Chloro-2- isopropylaminopyridin-4-yl)-1H-pyrrole-2-carboxylic acid [1 -(3-chlorophenyl)-2- hydroxyethyljamide.
The present invention provides a malonate salt of a compound of formula (I), which is a crystalline salt. Also provided are pharmaceutical compositions that include the provided malonate salt and methods of using the provided crystalline forms and pharmaceutical compositions for the treatment of cancer.
silyl ethers as intermediates that react with various electrophiles to generate defluorinated ketones as the products. Moreover, in combination with peroxide, a 1,2-shift of fluoroalkyl group is favored over deboronative fluoride elimination to generate ketal intermediates, leading to the formation of ketones as the products. This transition-metal-free reaction is operationally simple, and aryl, alkenyl
