Electric Literature of 69812-51-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 69812-51-7, name is Methyl 4-chlorosulfonylbenzoate, This compound has unique chemical properties. The synthetic route is as follows.
Methyl 4-[4-(2-Amino-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]-pyrimidin-6-yl)-N-methyl-methylaminosulfonyl]phenyl-4-carboxylate (compound5(0086) Compound 4 (2.77 g, 10 mmol) and methyl-4-chlorosulfonylbenzenecarboxylate (2.46 g, 10.5 mmol) were dissolved in 30 mL DMF. TEA (3.03 g, 3 eq) was added and the solution was stirred for 12 hours at room temperature. The solvent was removed and silica gel plaque was made. Column separation offered a purified white powder compound 5 in 80% yields, Rf0.25 (CHCl3/CH3OH, 10/1); 1H NMR (DMSO-d6) delta 1.26 (s, 9H), 2.60 (2, 3H), 4.21 (s, 2H, 6.25 (s, 1H), 7.94 (d, 2H), 8.06 (d, 2H), 10.91 (br, 1H), 11.63 (br, 1H), 11.91 (br, 1H).
The chemical industry reduces the impact on the environment during synthesis Methyl 4-chlorosulfonylbenzoate. I believe this compound will play a more active role in future production and life.
