2. 1-Bromo-3,5-dimethoxybenzene is used as an intermediate in the synthetic preparation of pharmaceutical inhibitors via cross-coupling reactions.

General Description

1-Bromo-3,5-dimethoxybenzene can be synthesized by using 1,3-dimethoxybenzene via iridium-catalyzed arene borylation.

Check Digit Verification of cas no

The CAS Registry Mumber 20469-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20469-65:
(7*2)+(6*0)+(5*4)+(4*6)+(3*9)+(2*6)+(1*5)=102
102 % 10 = 2
So 20469-65-2 is a valid CAS Registry Number.

Meta halogenation of 1,3-disubstituted arenes via iridium-catalyzed arene borylation

Murphy, Jaclyn M.,Liao, Xuebin,Hartwig, John F.

, p. 15434 - 15435 (2008/09/19)

We report the meta halogenation of 1,3-disubstituted arenes to form 3,5-disubstituted aryl bromides and chlorides by using iridium-catalyzed arene borylation chemistry. Iridium-catalyzed borylation of arenes with B2pin2, followed by reaction of the boronic ester with copper(II) bromide or chloride converts arylboronic esters to the corresponding aryl halides. A variety of arenes containing alkoxy, alkyl, halogen, nitrile, ester, amide, and pivaloyl and TIPS-protected alcohols were converted to the corresponding 3,5-disubstituted aryl bromides and chlorides in yields ranging from 46% to 85%. In addition, 2,6-disubstituted and 3-substituted pyridines were converted to the 4-halo and 5-halopyridines, respectively. The utility of this methodology was demonstrated by the formal conversion of nicotine to Altinicline in three steps with an overall yield of 61% using meta bromination of nicotine as the first step.

Grindstone chemistry: (Diacetoxyiodo)benzene-mediated oxidative nuclear halogenation of arenes using NaCl, NaBr or I2

Karade,Tiwari,Huple,Siddiqui

, p. 366 - 368 (2007/10/03)

A technique of "Grindstone chemistry" is applied to the solvent-free halogenation of arenes with NaCl, NaBr or I2 using (diacetoxyiodo)benzene as the oxidant. Improved yields and higher purities of the products are observed compared with those from established methods.
