Claim Text:
1. A process for preparing a crystalline polymorph comprising heating a slurry of (2-(4-(2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)-1H-pyrazol-1-yl)-2-methylpropanamide in isoamyl alcohol and then cooling the mixture whereby a Form B crystalline polymorph that exhibits an X-ray powder diffraction pattern having characteristic peaks expressed in degrees 2-theta at approximately 10.7, 14.0, 16.4, 18.6, 22.1, and 26.4 is formed.
