To 445 mg (2.44 mmol) 2-chloro-thiazole-4-carbonyl chloride in 8.0 mL dichloromethane is added a mixture of 0.38 mL (2.69 mmol) triethylamine and 1.35 mL (2.69 mmol) 2 molars solution of methylamine in THF. The mixture is stirred over night, concentrated and the residue is treated with water and NaHCO3 solution. After extraction with ethylacetate the organic phases are combined, dried (Na2SO4) and concentrated to yield the desired product
