Reaction Steps
In a round bottom flask, 3-amino-2,2-difluoropropanoic acid (500 mg, 4 mmol) was solubilized in MeOH (10 mL). At 0° C., SOCl2 (1 mL) was added dropwise. The reaction mixture was then stirred at room temperature overnight. Evaporation of the reaction mixture gave a white solid to be the product as HCl salt (570 mg, 81%). 1H NMR (400 MHz, DMSO-d6) δ ppm 3.63 (t, J=16 Hz, 2 H) 3.87 (s, 3 H) 9.07 (br. s., 2 H).
