Introduction of a new synthetic route about 153034-88-9

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. 153034-88-9, 2-Chloro-4-iodo-3-methylpyridine, other downstream synthetic routes, hurry up and to see.

Application of 153034-88-9 ,Some common heterocyclic compound, 153034-88-9, molecular formula is C6H5ClIN, 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.

To a solution of 2-chloro-4-iodo-3-methylpyridine (303 mg, 1.20 mmol) (Aldrich, catNo.724092), phenylboronic acid (160 mg, 1.32 mmol) (Aldrich, catNo.78181) and sodium carbonate (317 mg, 2.99 mmol) in tert-butyl alcohol (10 mL) and water (6 mL) was added Pd-127 (181 mg, 0.239 mmol). The resulting mixture was purged with N2, and then heated at 80 C. for 2 h. The reaction mixture was diluted with methylene chloride, washed with saturated NaHCO3, water and brine. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography on a silica gel column eluting with 10 to 20% ethyl acetate in hexanes to give the desired product (225 mg, 92%). LCMS calculated for C12H11ClN (M+H)+: m/z=204.2; found 204.2.

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. 153034-88-9, 2-Chloro-4-iodo-3-methylpyridine, other downstream synthetic routes, hurry up and to see.
