Sodium Hydroxide → 7-(Trifluoromethyl)isoquinolin-1-amine

Participants

Reaction Steps

A mixture of 1-phenoxy-7-(trifluoromethyl)isoquinoline (670 mg, 2.3 mmol), from above step D, and ammonium acetate (1.8 g, 23 mmol) was heated at 160° C. for 4 h. The mixture was cooled to room temperature and dissolved in water. Sodium hydroxide (1N solution) was added until the solution was basic and extracted with EtOAc (x4). The combined organic fractions were washed with saturated NaCl, dried over Na2SO4 and evaporated under vacuum to give the title compound.
