A pro-apoptotic solid dispersion comprises, a Bcl -2 family protein inhibitory compound of Formula A as defined herein, dispersed in a solid matrix that comprises (a) a pharmaceutically acceptable water-soluble polymeric carrier, and (b) a pharmaceutically acceptable surfactant. A process for preparing such a solid dispersion comprises subjecting to elevated temperature the compound of Formula A, the water-soluble polymeric carrier, and the surfactant to provide an extrudable semi-solid mixture; extruding the semi-solid mixture; and cooling the resulting extrudate to provide a solid matrix comprising the polymeric carrier, and the surfactant and having the compound dispersed in essentially non-crystalline form therein. The solid dispersion is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl -2 family proteins, for example cancer or an immune or autoimmune disease.

room temperature coupling of aldehydes with acetonitrile under base‐free conditions. The catalytic system is long‐lived and remarkably efficient with high turnover numbers (TONs) and turnover frequencies (TOFs) achieved. The mild reaction conditions allow a wide variety of aldehydes, including base‐sensitive ones, to catalytically react with acetonitrile.
