| Product | 4-(Bromomethyl)-2-(trifluoromethyl)thiazole | HCID 69441347 | 36% |
Reaction Steps
To a stirring solution of (2-(trifluoromethyl)thiazol-4-yl)methanol (550 mg, 3.00 mmol) in DCM (5 ml) was added PBr3 (0.283 ml, 3.00 mmol) at 0-5° C. in 5-10 min. and stirring continued for 1 h. Reaction mixture was diluted with DCM and washed with water. Organic layer was separated and distilled out to get crude product which was column purified using 0-2% EtOAC in hexane to get title compound in 36% yield.
