Abstract
In certain aspects, the invention provides a novel crystalline form of olaparib (4-[(3-[(4-cyclopropylcarbonyl)piperazin-4-yl]carbonyl)-4-fluorophenyl]methyl(2H)phthalazin-1-one). In related aspects, the invention provides a processe for preparing the novel crystalline form of olaparib. The process includes forming a solution comprising crude olaparib and an organic solvent; adding the solution to an anti-solvent to form a slurry comprising a precipitate; isolating the precipitate; and drying the precipitate to obtain a crystalline form III of olaparib.
