Abstract:
The present invention relates to certain salts of a 11-(2-pyrrolidin-1-yl-ethoxy)-14,19-dioxa-5,7,26-triaza-tetracyclo[19.3.1.1(2,6).1(8,12)]heptacosa-1(25),2(26),3,5,8,10,12(27),16,21,23-decaene (Compound I) which have been found to have improved properties. In particular the present invention relates to the citrate salt of this compound. The invention also relates to pharmaceutical compositions containing the citrate salt and methods of use of the citrate salt in the treatment of certain medical conditions.
Abstract:
A method for producing a lactam, which comprises subjecting an alicyclic primary amine to an oxidation reaction in the presence of a catalyst comprising a silicon oxide, to thereby obtain a lactam. A catalyst comprising a silicon oxide which is for use in the above-mentioned method.
Abstract:
A method of preparing .omega.-lactams, in particular caprolactam, comprising: a step of premixing cycloaliphatic acids having the formula ##STR1## where n=3-13, with a dehydrating agent; the first step of reaction with a nitrosating agent; the second step of reaction with the addition of a very small amount of water corresponding to a molar ratio U=H.sub.2 O/SO.sub.3 within the 0.1 to 0.9 range; and the step of reclaiming the unreacted cycloaliphatic acid. The method affords improved output from the lactamization reaction and reduced byproducts.
