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 (×4). The combined organic fractions were washed with saturated NaCl, dried over Na2SO4 and evaporated under vacuum to give the title compound.
