Procedure

A 25 ml round bottom flask was charged with 4-[4-azetidin-1-yl-6-(5-methyl-2H-pyrazol-3-ylamino)-pyrimidin-2-ylsulfanyl]-benzoic acid (200 mg, 0.48 mmol), cyclopentyl amine (85 mg, 1 mmol), 2-(1H-benzotriazol-1-yl)-1,1,3,3,-tetramethyluroniumtetrafluoroborate (321 mg, 1 mmol), diisopropylethylamine (0.34 ml, 2 mmol) in dimethylformamide (5 ml), under nitrogen. The reaction mixture was stirred at room temperature for 18 hours and then was diluted with ethyl acetate (40 ml), washed with a saturated sodium hydrogen carbonate aqueous solution (40 ml) and brine (40 ml). The organic was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was triturated in dichloromethane to afford the title compound. 1H NMR (DMSO-d6): 1.60-1.65 (4H, m), 1.70-1.80 (2H, m), 1.95-2.10 (5H, m), 2.20-2.30 (2H, m), 3.90-4.00 (4H, s), 4.30-4.35 (1H, m), 5.35-5.40 (1H, s), 7.70-7.75 (2H, d), 8.00-8.05 (2H, d), 8.45-8.50 (1H, d), 9.3 (1H, s). MS (ES+): 450.
