Electric Literature of 374554-89-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 374554-89-9, 3-Chloro-6-fluorobenzo[d]isoxazole, introducing its new discovery.
Certain anti-inflammatory pyrazolo [4,3-b] pyridine 7-amines
A compound of the formula (1) or a salt or solvate thereof: STR1 in which: R0 is hydrogen or C1-6 alkyl; R1 and R2 are both hydrogen; or R1 is hydrogen, C1-6 alkyl; and R2 is CN; CR5 R6 Y where R5 and R6 are independently selected from hydrogen and C1-4 alkyl and Y is selected from hydrogen, OR7 or SR7 where R7 is hydrogen, C1-4 alkyl or C2-4 alkanoyl, and NR8 R9 where R8 and R9 are independently hydrogen, C1-4 alkyl, C2-4 alkenyl or C2-4 alkanoyl or together are C4-6 polymethylene; or COR10 is OH or C1-4 alkyl, or COR10 is a pharmaceutically acceptable ester or amide; or R2 is hydrogen, C1-6 alkyl, or phenyl optionally substituted by halogen, CF3, C1-4 alkoxy or C1-4 alkyl; and R1 is CN, CR5 R6 Y or COR10 as defined for R2 above; or R1 and R2 together form C3 -C6 polymethylene optionally substituted by C1 -C4 alkyl; R3 is –(CH2)n CO2 R11, –(CH2)n CONR12 R13,–(CH2)n CN, –(CH2)m NHCOR14, STR2 where a, b, n, m and p are integers and n is 1 to 10, m is 2 to 10, p is 3 to 5, a is 1 to 3, and b is 1 to 3, and R11 is hydrogen, C1-8 alkyl, benzyl or phenyl, R12 and R13 are independently hydrogen, C1-6 alkyl, benzyl or phenyl, or together form C3-8 alkylene, R14 is C1-4 alkyl, benzyl or phenyl and X is oxygen, sulphur, NH or N–C1-4 alkyl, and R4 is hydrogen; or C1-4 alkyl or benzyl optionally substituted in the phenyl ring by one or two of halogen, CF3, C1-4 alkoxy or C1-4 alkyl, and is attached at nitrogen atom 1 or 2, a process for its preparation and its use as a pharmaceutical.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 374554-89-9, you can also check out more blogs aboutElectric Literature of 374554-89-9
