Reference of 915087-25-1, These common heterocyclic compound, 915087-25-1, name is 4-Amino-2-fluoro-N-methylbenzamide, 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.
A mixture of 4-amino-2-fluoro-N-methylbenzamide (2 g, 11.9 mmol), TMSCN (2.2 mL, 17.9 mmol), TMSOTf (0.1 mL, 0.6 mmol), and acetone (10 mL, 140 mmol) in DCM (20 mL) was stirred at room temperature overnight. The white solid was filtered, washed with a small amount of DCM, and dried to afford 1.12 g of 4-((2-cyanopropan-2-yl)amino)-2-fluoro- N-methylbenzamide as a white solid. lR NMR (300 MHz, DMSO-d6) delta 7.79 (t, 1H), 7.56 (t, 1H), 6.88 (s, 1H), 6.67 (dd, 1H), 6.54 (dd, 1H), 2.75 (d, 3H), 1.67 (s, 6H).
Statistics shows that 4-Amino-2-fluoro-N-methylbenzamide is playing an increasingly important role. we look forward to future research findings about 915087-25-1.
