Procedure

4-amino-5-(4-amino-3-fluorophenyl)pyrrolo[2,1-f][1,2,4]triazine-6-carboxylic acid (24.6 g, 85.6 mmol) was added to a mixture of 2,2,2-trifluoro-1-aminoethane (42.4 g, 428 mmol), benzotriazolyloxytris(dimethylamino)phosphonium PF6 (56.8 g, 128 mmol) and 4-methylmorpholine (43.3 g, 428 mmol) in DMF (500 mL). The reaction mixture was stirred at rt for 16 h. The resulting precipitate was isolated by filtration and then washed with acetone and diethyl ether to give the desired product (22 g, 70%); 1H NMR (300 MHz, DMSO-d6) δ 8.37 (dd, J=8.5, 8.5 Hz, 1H), 8.12 (s, 1H), 7.94 (s, 1H), 7.92-8.03 (br s, 1H), 7.89 (s, 1H), 6.99 (dd, J=12.2, 1.8 Hz, 1H), 6.85 (dd, J=12.2, 1.8 Hz, 1H), 6.74-6.6.82 (m, 1H), 5.35 (s, 2H), 5.13-3.22 (br s, 1H), 3.87-4.01 (m, 2H); ES-MS m/z 369.2 (MH)+; HPLC RT (Method B) 2.05 min.
