The present disclosure relates to an improved, efficient, scalable process to prepare intermediate compounds, such as 2-isopropyl-4-methylpyridin-3-amine, useful for the synthesis of compounds, such as Compound 9, for the treatment of KRAS G12C mutated cancers.
The 17ONMRspectra of a number of alkyl‐ and phenyl‐substituted divinyl ethers were recorded in CDCl3 solution. The relationship between chemical shift and the number, nature and position of substituents was explored. The shift values, falling in the range δ 100–140 ppm, were found to be remarkably insensitive to the electronic and stereochemical effects of substituents. The narrow range of chemical
Compounds of the formula (I) ##STR1## where X.sup.1 and X.sup.2 independently of one another are halogen or haloalkyl, R.sup.1 is hydrogen, alkyl or alkoxyalkyl, R.sup.2 is alkyl or haloalkyl, and R.sup.3 is hydrogen, alkyl, alkenyl or alkynyl, can reduce, or entirely compensate, phytotoxic secondary effects of herbicides on crop plants and are therefore suitable as agents for the selective use of herbicides.
This disclosure relates to new heterocyclic compounds that may be used to modulate a histamine receptor in an individual. Pyrido[3,4-b]indoles are described, as are pharmaceutical compositions comprising the compounds and methods of using the compounds in a variety of therapeutic applications, including the treatment of a cognitive disorder, psychotic disorder, neurotransmitter-mediated disorder and/or a neuronal disorder.
