In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 166591-85-1, name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, introducing its new discovery. Application In Synthesis of 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid
CRYSTALLINE ALFUZOSIN BASE
The present invention relates to crystalline alfuzosin base and processes for preparation of the said crystalline solid. Thus, for example, alfuzosin base (HPLC purity: 97%) is added to methanol and heated to reflux to form a clear solution, the solution is cooled to 25 – 30C and stirred for 12 hours at the same temperature, the resulting solution is cooled to 10- 15C and stirred for 2 hours, and the resulting solid is filtered, washed with methanol and dried at 50- 60C for 4 hours to give 99.95% pure alfuzosin base.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 166591-85-1, and how the biochemistry of the body works.Application In Synthesis of 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid
