Reaction Steps

A 0.5 g sample of technical grade olanzapine was suspended in ethyl acetate (10 mL) and toluene (0.6 mL). The mixture was heated to 80° C. until all the solids dissolved. The solution was cooled to 60° C. and water (1 mL) was added slowly. As the solution cooled to room temperature, a crystal slurry formed. The product was isolated using vacuum filtration and dried under ambient conditions. The product was identified as Dihydrate E using x-ray powder analysis and solid state 13C NMR. TGA mass loss was 10.5%. Yield: 0.3 g.
