Versuchsvorschrift

To a mixture of 3-methyloxetane-3-carboxylic acid (8.7 mg, 0.075 mmol) and HATU (28.5 mg, 0.075 mmol) was added a solution of crude 4-(6-iodo-1H-indazol-1-yl)pyrimidine-2,5-diamine (11% purity, 120 mg, 0.037 mmol) in DMF (0.5 mL) followed by triethylamine (0.016 mL, 0.112 mmol). The mixture was stirred at RT for 10 min, then diluted with EtOAc (10 mL) and washed with water (2×3 mL). The combined organic layer was dried over Na2SO4, filtered and concentrated in vacuo to give the crude compound. Purification by flash chromatography (Isolute column, 100% DCM to 3% MeOH in DCM) gave the title compound; m/z=+451.30 (M+H)+, (purity=76%). This intermediate was used in the next step without further purification.
