Tetrahydrofuran → HCID 2774059, compound

Participants

Reaction Steps

Into 50 ml of tetrahydrofuran, were added 3.5 g of 2-amino-4-phenylthiazole and 2.0 g of triethylamine. The mixture was cooled to 0°--5° C. Then, 4.3 g of α-bromopropionylbromide was dropped to the solution mixture. After the completion of the dropwise addition, the solution mixture was stirred at room temperature for 1 hour. Then, the reaction mixture was concentrated under reduced pressure. The residue was taken up in chloroform and washed with water. Upon removal of chloroform, a crude reaction product was obtained. It was thereafter subjected to silica gel chromatography and then eluted with a chloroform/methyl alcohol (40:1) mixed solvent. It was then recrystallized from an ether/cyclohexane mixed solvent, thereby obtaining 4.2 g of 2-(α-bromopropionylamino)-4-phenylthiazole.
