A solution of 2-Benzyloxymethyl-5-bromo-thiazolo[5,4-b]pyridine (1.60 g, 4.77 mmol) DCM (15 mL) was cooled to −78° C. followed by addition of BBr3 (2.27 ml, 23.86 mmol). The reaction mixture was stirred at 25° C. for 2 h. After the completion of the reaction mixture (TLC monitoring), solution of NaHCO3 (20 mL) was added at 0° C. and extracted with ethyl acetate (3×50 mL). The combined organics was washed with water, brine, dried (Na2SO4), filtered and concentrated to get the desired product (2.0 g, Crude yield).
