Procedure

The mixture of Pd(dppf)Cl2.CH2Cl2 (74 mg, 0.09 mmol, 0.15 eq.), 2-bromo-5-chloro-N-(5-(trans-2-methylcyclopropyl)-1H-pyrazol-3-yl)pyrimidin-4-amine (200 mg, 0.61 mmol, 1.0 eq), 5-(N-tert-butylsulfamoyl)thiophen-2-ylboronic acid (192 mg, 0.73 mmol, 1.2 equiv.) and saturate Ka2CO3 (5 mL) in dioxane (10 mL) was heated to 90° C. for 1 h under nitrogen atmosphere. The reaction mixture was cooled to rt, and extracted with THF. The combined layers were purified by silica gel chromatography (EtOAc/Petroleum ether from 10:1 to 2:1) to afford compound N-tert-butyl-5-(5-chloro-4-(5-(trans-2-methylcyclopropyl)-1H-pyrazol-3-ylamino)pyrimidin-2-yl)thiophene-2-sulfonamide (180 mg, 63%).
