실험 절차

A solution of TFA (0.916 mL, 12.0 mmol) and tert-butyl 3-(4-((4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)azetidine-1-carboxylate (A9) (174 mg, 0.299 mmol) in DCM (10 mL) was stirred for 16 hours at room temperature under nitrogen. The volatiles were removed in vacuo and the residue was taken up in MeOH and loaded onto an SCX cartridge (10 g). The column was eluted with 5 column volumes of MeOH and then 5 column volumes of 5% v/v aqueous ammonia in MeOH to elute the amine product. The ammoniacal filtrate was evaporated under reduced pressure and dried under high vacuum to give the title compound 4 as a yellow solid (129 mg, 90%); 1H NMR (400 MHz, d6-DMSO) δ 10.19 (s, 1H), 8.68 (s, 1H), 7.77-7.67 (m, 2H), 7.38-7.26 (m, 5H), 7.26-7.18 (m, 1H), 6.99 (s, 1H), 6.00 (s, 2H), 3.86 (s, 3H), 3.71 (s, 2H), 3.22-3.13 (m, 2H), 3.13-3.05 (m, 2H), 1.44 (s, 2H), 0.96 (s, 2H). LCMS-A: rt 4.591 min; m/z 482 [M+H]+.
