Conditions

Temperature: 60 °C

Procedure

TFA (1 mL) was added to a solution of tert-butyl 4-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-oxopiperazine-1-carboxylate (10 mg, 0.015 mmol) and anisole (6.53 μl, 0.060 mmol) in DCE (1 mL) and the reaction mixture was heated at 60° C. for 30 min. LC-MS indicated completion, then it was cooled and concentrated. The crude was dissolved in methanol and neutralized with 7N ammonia in methanol. After stirring for 10 min it was concentrated, purification via preparative HPLC gave the title compound as a yellow solid (3.8 mg).
