    摘要: Systems and methods to provide an availability and price determination, in response to a request for function space, to a user in real-time. For one embodiment, a request for a function space is received at a digital processing system that contains availability information and a set of pricing rules for one or more function spaces. The request includes a plurality of criteria. An availability of the requested function space is determined based upon the availability information and one or more of the criterion. A price for the requested function space is determined based upon the set of pricing rules and one or more of the criterion.

    摘要: A method for the preparation of montelukast acid sodium salt thereof in amorphous form has been described. The method comprises of following steps: (a) generating the dilithium dianion of 1-(mercaptomethyl)cyclopropane acetic acid, by reacting with alkyl lithium, (b) coupling the said dianion with wet mesylate to get montelukast acid in crude form, (c) obtaining DCHA salt in crude form by adding dicyclohexylamine (DCHA) to crude acid obtained in the above step (b), (d) purifying and converting the said DCHA salt in crude form, to montelukast acid in pure form, and (e) reacting the pure montelukast acid in a polar protic solvent with a source of sodium ion followed by evaporating the solvent and triturating of the residue with non-polar water immiscible solvent.
