Reaction Steps
A solution of 2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (313 mg, 1.256 mmol), 2-(4-iodo-1H-pyrazol-1-yl)-N,N-dimethylethanamine (Preparation 62, 270 mg, 1.019 mmol) and Pd(dppf)Cl2.DCM (80 mg, 0.098 mmol) was dissolved in THF (4.5 mL) and 2M sodium carbonate in water (1.5 mL) and heated to 60° C. for 18 hours. The mixture was concentrated under reduced pressure. The residue was partitioned between water and DCM and the aqueous layer extracted with DCM three times. The combined organic layers were dried and concentrated. The residue was purified by silica gel column chromatography eluting with 0 to 10% MeOH in DCM to give the title compound (74 mg, 28%).
