Sodium hydroxide (36.5 ml, 36.5 mmol) was added to a solution containing 2-(trichloromethyl)-benzo[4,5]imidazo[1,2-a]pyrimidine (8.04 g, 28.1 mmol) in Acetonitrile (Volume: 122 ml). Heated the reaction to 90 C for 30 minutes. Cooled the reaction to room temperature and concentrated. Added ice to the resulting residue, followed by 35 mL of 1M HCl. Filtered the solid and dried under vacuum to afford crude benzo[4,5]imidazo[1,2-a]pyrimidin-2-ol (5.2 g, 28.1 mmol, 100% yield).
