Procedure
The mixture of (S)-4-(7-(3-methoxy-5-(2-methylpyrrolidin-1-yl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzoic acid, EDCI (56 mg, 0.29 mmol), HOBt (39 mg, 0.29 mmol) and Et3N (39 mg, 0.39 mmol) in DCM (20 mL) was stirred at room temperature for 3 hrs, then ammonia was bubbled into this mixture for 3 h. The mixture was filtered and the filtrate was concentrated to give a residue which was purified by column chromatography (DCM:MeOH=50:1) to afford (S)-4-(7-(3-methoxy-5-(2-methylpyrrolidin-1-yl)phenylamino)thiazolo[5,4-d]pyrimidin-5-yl)benzamide (12 mg, 10%) as yellow solid. 1H NMR (300 MHz, DMSO): δ 9.99 (s, 1H), 9.40 (s, 1H), 8.49 (s, 1H), 8.46 (s, 1H), 8.12 (s, 1H), 8.01 (s, 1H), 7.98 (s, 1H), 7.49 (s, 1H), 7.15 (s, 1H), 7.05 (s, 1H), 5.88 (s, 1H), 3.93-3.90 (m, 1H), 3.79 (s, 3H), 3.43-3.40 (m, 1H), 3.18-3.15 (m, 1H), 2.06-1.98 (m, 3H), 1.69 (s, 1H), 1.15 (d, 3H, J=6.0 Hz). LC-MS: 461 [M+H]+, tR=1.6 min. HPLC: 95.06% at 214 nm, 95.01% at 254 nm, tR=5.55 min.
