The occurrence of different crystalline forms of ibrutinib and salts thereof gives rise to a variety of polymorphs having distinct crystal structures and physical properties like melting point, thermal behaviors. Polymorphic forms of the compound are important in that the forms having desirable characteristics, such as ease of handling, ease of processing, ease of formulating, storage stability, ease of purification, improved dissolution or bioavailability, or form that facilitates conversion to another desirable polymorphic form. Thus, new polymorphic forms of ibrutinib are useful for providing the compound having desirable characteristics. For at least these reasons, there is a need for additional polymorphic forms of ibrutinib.

Amorphous compounds are considered solid state forms of polymorphs, which are chemically identical to other polymorphs but have different physical properties such as crystal lattice energies, melting points, intrinsic solubilities, rates of dissolution, densities, mechanical properties, chemical and physical stability, hygroscopicity, and morphology. The differences in intrinsic solubilities also may lead to differences in the rate of absorption, thus impacting bioavailability. Amorphous ibrutinib is moisture stable. It is therefore a good alternative to crystalline ibrutinib as amorphous material has a higher solubility, which is connected with better bioavailability, than corresponding crystalline forms. For at least these reasons, there is also a need for processes to prepare amorphous ibrutinib. SUMMARY OF THE DISCLOSURE

Techniques for characterizing crystal and amorphous forms include, but are not limited to differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), X-ray powder diffractometry (XRPD), proton nuclear magnetic resonance (¹H- MR) and Optical Microscopy.

DSC data are collected using a TA Instruments Q10 DSC. Approximately, samples (2-8 mg) are placed in unsealed but covered hermetic alodined aluminum sample pans and scanned from about 30 to about 300 °C at a rate of about 10 °C/min under a nitrogen purge of about 50 mL/min.

Modulated DSC data are collected using a TA Instruments Q2000 equipped with an auto-sampler and RSC40. Samples are equilibrated at 5 °C in Tzero hermetically sealed aluminum pans with a ramp rate of 1.5 °C/min to 200 °C under a nitrogen purge of about 50 mL/min, modulated ±0.50 °C every 60 seconds in T4P (or T4) mode.

Samples are placed on zero-background, silicon plate holders for analysis. One skilled in the art would recognize that the °2Θ values and the relative intensity values are generated by performing a peak search on the measured data and the <i-spacing values are calculated by the instrument from the °2Θ values using Bragg' s equation.
