Acetone → HCID 23367237, compound

To a solution of 2-methylthiazoline (10.1 g) in dioxane (20 ml) was added 2-bromoethanol (13.8 g), and the mixture was heated under reflux for about 6 hours. After cooling the reaction, acetone (30 ml) and ether (130 ml) were added with stirring, and the resulting mixture was left standing. After the pale brown supernatant was discarded, ether (150 ml) was further added to the amorphous precipitate thus obtained. The mixture was stirred and left standing. Supernatant obtained was discarded, and the viscous precipitates obtained was left standing at an ambient temperature under reduced pressure to give the title compound as the yellow amorphous residue.
