Versuchsvorschrift

DIPEA (0.4 mL, 2.08 mmol) was added to a suspension of 4-(3-[(1S)-2-hydroxy-1-methylethoxy]-5-{[(5-methylpyrazin-2-yl)amino]carbonyl}phenoxy)benzoic acid (110 mg, 0.26 mmol), HATU (210 mg, 0.55 mmol) and azetidine hydrochloride (49 mg, 0.52 mmol) in DMF (3 mL) and the mixture stirred at RT for 24 hours. Water (30 mL) was added and the mixture extracted with ethyl acetate (3×15 mL). The combined organic extracts were washed with brine, dried (MgSO4), and evaporated to a residue which was chromatographed on silica, eluting with 5% methanol in ethyl acetate, to give the desired compound (55 mg).
