Reaction Steps
Methyl(2-tert-butoxycarbonylamino 1,3-thiazole-5-yl)acetate (4.08 g, 15 mmol) in dioxane (60 ml) was reacted with selenium dioxide (4 g, 36 mmol) at reflux for 45 minutes. The mixture was cooled, CH2Cl2/MeOH 8/2 (150 ml) was added, the insoluble material was filtered, the organic phase was washed with a saturated solution of sodium bicarbonate, and extracted with CH2Cl2, dried, purified by chromatography over alumina, eluant CH2Cl2/MeOH 9/1 to give title compound (1 g, 23%).
