Abstract: The present invention relates to a method of preparing a compound represented by structural formula (VII), comprising reacting a compound represented by structural formula (II), with a compound represented by structural formula (III), in a solvent, in the presence of a Pd catalyst and one or more inorganic bases under conditions suitable to prepare a compound represented by structural formula (VII): The values and example values of the variables in structural formulas (VII), (II), and (III) are defined herein. The present invention also relates to crystalline Forms I and II of the compound represented by Structural Formula (VII), the use of the crystalline Forms in treating disease or disorders associated with CRM1 and method of preparing the crystalline Forms.

Abstract: The disclosure provides methods of forming one or more single-cell proteomic samples, such as by: dispensing n droplets of lysis buffer onto a substantially planar solid surface, wherein n>2: dispensing a single cell into each of the n droplets of lysis buffer to produce n droplets with a lysed single cell: dispensing digestion buffer into each of the n droplets to digest proteins from each lysed single cell to produce n droplets comprising peptides: dispensing a chemical tag into at least a subset of the n droplets comprising the peptides to produce labeled peptides, thereby enabling the labeled peptides in a given droplet to be distinguishable from labeled peptides in at least one other droplet: and applying a fluid to merge at least a subset of the droplets into a combined droplet on the substantially planar surface, thereby combining the labeled peptides to form a single-cell proteomic sample.
