New downstream synthetic route of 14192-26-8

Synthetic Route of 14192-26-8, These common heterocyclic compound, 14192-26-8, name is Methyl 2-oxoindoline-6-carboxylate, 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.

Synthetic Route of 14192-26-8, These common heterocyclic compound, 14192-26-8, name is Methyl 2-oxoindoline-6-carboxylate, 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.

Room temperature, 2-indolone-6- methyl formate(5-2) (4.0g, 20 . 71mmol) suspended in 12 ml in toluene of, the chloroactic anhydride (5.4g, 30 . 95mmol) into the above-mentioned suspension, heating reflow 3h, cooling to 80 C, 30 min by adding methyl cyclohexane (6 ml), stirring suspension of cooling to room temperature, filtered to obtain crude products, with cold methanol (4 ml) washing, drying the white solid obtained 5.155g (93.5%), i.e. compound 1-cholroacetyl- 2-indolone-6- methyl formate (6-2).

The synthetic route of 14192-26-8 has been constantly updated, and we look forward to future research findings.
