06/9/2021 News The origin of a common compound about 585-48-8

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. 585-48-8, 2,6-Di-tert-butylpyridine, other downstream synthetic routes, hurry up and to see.

Application of 585-48-8 ,Some common heterocyclic compound, 585-48-8, molecular formula is C13H21N, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

EXAMPLE 197 (R)-N-(2-Chloro-4-iodophenyl)-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide Oxalyl chloride (1.07 ml) was added dropwise to a stirred suspension of (R)-(+)-2-hydroxy-2-methyl-3,3,3-trifluoropropanoic acid (Method 9) (1.95 g) in DCM (42 ml) and DMF (0.8 ml). The mixture was stirred at ambient temperature for 2 hours and was then added over 35 minutes to a solution of 2-chloro-4-iodoaniline (2.5 g) and 2,6-di-t-butylpyridine (2.94 ml) in DCM (40 ml) and stirred a further 18 hours. Volatile material was removed by evaporation and the residue was purified by flash chromatography on silica gel eluding with DCM to give the title compound (2.85 g) as a solid. NMR: 1.6 (s, 3H), 7.7 (m, 2H), 7.8 (d, 1H), 7.9 (brs, 1H); MS (ESP-): 392.
