HCID 154758374-(1,3-Thiazol-2-yl)morpholineYield 95%

Conditions

Temperature
100 °C

Procedure

2-Bromothiazole (4.592 g) was added to morpholine (24 ml), and the mixture was stirred at 100° C. for 4 hr. The reaction mixture was partitioned between ethyl acetate and water. The resulting organic layer was washed with water, dried (over MgSO4) and evaporated. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane system) to give the title compound as a pale yellow oil (4.531 g, yield; 95%).
