Related Products of 1422-54-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1422-54-4, name is 2-Bromo-6-fluorotoluene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 187 6-(3-Fluoro-2-methylphenyl)-1,2-dihydro-2,2,4-trimethylquinoline (Compound 287, structure 4 of Scheme II, where R1 =3-fluoro-2-methylphenyl) This compound was prepared by General Method 2 (EXAMPLE 9) from Compound 9 (50 mg, 0.158 mmol) and 2-bromo-6-fluorotoluene (60 mg, 0.315 mmol). Purification by flash chromatography on silica gel (20g) using 5% EtOAc:hexanes afforded 6 mg(14%) of Compound 287 as a yellow oil. Data for Compound 287: 1 H NMR (400 MHz, acetone-d6) 7.20 (m, 1H), 7.02 (m, 1H), 6.98 (m, 2H), 6.91 (m, 1H), 6.56 (d, J=8.0, 1H), 5.37 (s, 1H), 5.37 (s, 1H), 5.29 (br s, 1H), 2.19 (s, 3H), 1.98 (s, 3H), 1.28 (s, 6H).
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, 2-Bromo-6-fluorotoluene, other downstream synthetic routes, hurry up and to see.
