Reaction Steps
To a microwave vial was added N,N-diisopropylethylamine (0.86 ml, 4.9 mmol), 2,4-dibromothiazole (1.00 g, 4.1 mmol), and morpholine (0.43 ml, 4.9 mmol) in EtOH (4 mL). The mixture was heated under microwave irradiation at 140° C. for 35 minutes. The reaction mixture was concentrated in vacuo. The crude material was dissolved in minimal DCM/MeOH and purified via MPLC (eluting with 0-30% EtOAc in hexanes) to yield 4-(4-bromothiazol-2-yl)morpholine (0.700 g, 68% yield) as a white solid.
