Application of 100510-65-4, The chemical industry reduces the impact on the environment during synthesis 100510-65-4, name is 6-Amino-3,3-dimethylindolin-2-one, I believe this compound will play a more active role in future production and life.
EXAMPLE G N-Propyl-N’-[2,3-dihydro-3,3-dimethyl-2-oxo-(1H)-indol-6-yl]-urea 3.52 g. (0.02 mole) 6-amino-2,3-dihydro-3,3-dimethyl-(1H)-indolin-2-one are suspended in 40 ml. anhydrous dioxan and mixed at ambient temperature within the course of 10 minutes with a solution of 1.7 g. (0.02 mole) n-propyl isocyanate in 10 ml. dioxan, whereupon a clear solution is formed. Shortly thereafter, the product begins to separate out as a crystalline mass. After 1 hour, the suspension is mixed with ligroin and the precipitate is filtered off with suction, washed with ligroin and diethyl ether and recrystallized from ethanol. Yield 3.91 g. (75% of theory); m.p. 223-225 C.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6-Amino-3,3-dimethylindolin-2-one, other downstream synthetic routes, hurry up and to see.
