Chloroacetyl Chloride (5.0 mL, 44.5 mmol) was added to N-Hydroxy-thiazole-2-carboxamidine (0.50 g, 3.49 mmol) and K2CO3 (1.0 g, 7.20 mmol). The reaction mixture was heated at 100° C. for 15 min. After the completion of the reaction mixture (TLC monitoring), water (25 mL) was added and extracted with ethyl acetate (3×50 mL). The combined organics was washed with water, brine, dried (Na2SO4), filtered and concentrated. The crude residue was purified over silica gel (230-400 M, 10% EtOAc-Hexane) to get the desired product (0.18 g, 25%) as a white solid.
