Reaction Steps

To a mixture of 2-amino-5- bromothiazole monohydrobromide (2 gm, 7.69 mmol) and powdered potassium carbonate (2.1 gm, 15.38 mmol) in DMF (20 mL) was added morpholine (1.34 ml, 15.38 mmol) under argon atmosphere and heated at 60° C. for 3 hr. Reaction mixture was cooled to rt and poured over ice cold water (100 ml), extracted with ethylacetate (3×100 ml), washed with brine solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. To the residue, diisopropyl ether (50 mL) was added, after stirring for 30 minutes product precipitated out, which was filtered and dried under vacuum to provide 5-morpholin-4-yl-thiazol-2-ylamine (0.95 gm).
