Reaction Steps

6N HCl aq. (1.1 mL) was added to a mixture of 3-(4-(1H-naphtho[1,8-de][1,3,2]diazaborinin-2(3H)-yl)phenyl)pyridin-2-amine (396 mg) in THF (dry) (12 mL). The mixture was stirred at room temperature for 3 hr. The mixture was added with sat. NaHCO3 aq, EtOAc and 2N NaOH aq., and the separated aqueous phase was acidified by 6N HCl aq., then controlled pH ca.8 by sat. NaHCO3 aq. The aqueous mixture was extracted with EtOAc, and the organic layer was separated, washed with brine dried over anhydrous magnesium sulfate and concentrated in vacuo to give the title compound (52.4 mg) as a white solid.
