Related Products of 49851-36-7, These common heterocyclic compound, 49851-36-7, name is Methyl 2-(2-aminophenyl)acetate hydrochloride, 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.
ln a 40 mL vial, HATU (2.263 g, 5.95 mmol) was added in one portion at room temperature to a DMF solution (10 mL) of methyl 2-(2-aminophenyl)acetate hydrochloride (CAS 49851-36-7) (1g, 4.96 mmol), 6-chloropyridine-2-carboxylic acid (CAS 4684-94-0) (0.938 g, 5.95 mmol) and DIEA (2.165 mL, 12.40 mmol). The resulting solution was allowed to stir at room temperature (2.5 hr). The reaction was diluted with ethyl acetate, washed with water (twice) and a saturated aq. NaCI solution. The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified via FCC (10:1 Heptane/ethyl acetate to 1 :1 Heptane/ethyl acetate) to give the title compound. MS (ESI+) m/z 305.3 (M+H).
Statistics shows that Methyl 2-(2-aminophenyl)acetate hydrochloride is playing an increasingly important role. we look forward to future research findings about 49851-36-7.
