A mixture of {5-[bis(methyloxy)methyl]-3-bromo-2-pyridinyl}methanol (98 mg, 0.374 mmol) and 1N HCl (3.26 mL, 3.26 mmol) in DCM (5 mL) was stirred overnight. DCM and 1M NaOH solution were added. Extraction, drying (Na2SO4), and filtration afforded 5-bromo-6-(hydroxymethyl)-3-pyridinecarbaldehyde (70 mg, 87%) as a brown oil pure enough to be used in the next step.
