Procedure

Methyl thiourea (0.492 g, 2.28 mmol, 1.1 eq) was dissolved in EtOH (dried over mol. sieves) (2 ml) and triethyl amine (0.633 ml, 2.2 eq) was added. Reaction mixture was heated to 70° C. and 2-(acetoxy-thiazol-2-yl-methyl)-acrylic acid methyl ester (0.5 g, 2.07 mmol, 1 eq) dissolved in EtOH (dried over mol. sieves) (2 ml), was added. It was heated at 70° C. for 8 h and then, it was cooled and filtered. Filtrate was evaporated to dryness and purified via Biotage SP 1 Snap 25 g, 25 ml/min; in system MeOH/DCM 1-30% MeOH in 30 CV. Appropriate fractions were combined and evaporated to give 250 mg of brown powder.
