实验过程

To a suspension of 2-chloroacetamide (50.00 g, 524.01 mmol) in 100 mL of acetonitrile was added pyridine (41.45 g, 524.01 mmol). After being stirred at 90° C. for 10 h, the suspension was cooled to 22° C., suction-filtered and washed with 100 mL of hexanes. The product, 1-(2-amino-2-oxoethyl)pyridinium chloride (79.10 g, yield: 87%, mp 205.2° C.), was obtained as colorless crystals after being recrystallized from methanol.
