Procedure

A mixture of 5-(3-aminopyrrolidin-1-yl)-N-(3,4-dimethoxyphenyl)thiazolo[5,4-d]pyrimidin-7-amine hydrochloride (100 mg, 0.245 mmol), 6-aminonicotinic acid (40 mg, 0.27 mmol), EDCI (97 mg, 0.49 mmol) and N-methylimidazole (60 mg, 0.735 mmol) in 5 mL of DCM was stirred at room temperature for 16 hours. The mixture was washed with water (5 mL), The organic layer was dried over Na2SO4. After filtration and concentration, the residue was purified by column chromatography on silica gel eluting with a mixture of CH2Cl2 and methanol (100:1→15:1) to give 6-amino-N-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-yl)nicotinamide (40 mg, 33%). 1H NMR (300 MHz, DMSO): δ 9.57 (s, 1H), 8.81 (s, 1H), 8.475-8.46 (m, 1H), 8.27-8.25 (m, 2H), 7.60-7.25 (m, 2H), 6.92 (d, 1H, J=8.7 Hz), 6.47-6.39 (m, 3H), 4.54-4.52 (m, 1H), 3.76-3.58 (m, 10H), 2.34-2.04 (m, 2H). LC-MS: 247 [M/2+H]+, 493 [M+H]+, 491 [M−H]−, tR=1.22 min. HPLC: 95.20% at 214 nm, 95.06% at 254 nm, tR=5.64 min.
