Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, below Introduce a new synthetic route., 36216-80-5
EXAMPLE 12 3-[(4-pyridinyl)amino]-1,2-benzisoxazole A mixture of 3-amino-1,2-benzisoxazole (9.94 g, 74.18 mmole, prepared according to a method described in G. M. Shutske and K. J. Kapples, J. Heterocyclic Chem., 26, 1293 (1989)), 4-chloropyridine hydrochloride (22.27 g, 197 mmole) and 1-methyl-2-pyrolidinone was stirred vigorously at 130 C. for three hours. The reaction mixture was cooled, diluted with NaHCO3, and extracted with EtOAc, after which the organics were washed with water, dried (MgSO4), and concentrated. The residue was purified by flash chromatography (florisil, EtOAc), and then triturated with diethyl ether to yield 4.04 g (26%) of a fine brown solid. A 2.0 g portion was dissolved in boiling methanol and treated with charcoal (Darco) after which the product crystallized to yield 1.38 g of pale yellow crystals, mp 203 C. (dec.). ANALYSIS: Calculated for C12 H9 N3 O: 68.24% C; 4.29% H; 19.89% N; Found: 68.14% C; 4.12% H; 20.06% N.
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. 36216-80-5, other downstream synthetic routes, hurry up and to see.
