Dibah → (2-Bromo-4-fluorobenzo[d]thiazol-6-yl)methanol

Participants

Reaction Steps

To a solution of methyl 2-bromo-4-fluorobenzo[d]thiazole-6-carboxylate (0.335 g, 1.15 mmol) in toluene (10 mL) and THF (5 mL) was added Dibal-H (4.8 mL, 4.8 mmol) at −78° C. over 10 min. The resulting mixture was allowed to warm to rt and stirred at rt for 3 hr before it was poured into ice cold water (100 mL). The mixture was stirred at rt for 30 min and then filtered through Celite® 545. The organic layer was separated and the aqueous layer was extracted twice with AcOEt. The combined organic phase was dried over anhydrous MgSO4 and concentrated under vacuum. Evaporation of solvent under vacuum gave the title compound (0.269 g, 89% yield) as a white solid.
