Procedure

DIPEA (0.28 mL, 1.59 mmol) was added to a suspension of 5-[(3-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}-5-{[(1-methyl-1H-pyrazol-3-yl)amino]carbonyl}phenyl)oxy]pyrazine-2-carboxylic acid (170 mg, 0.4 mmol), HATU (318 mg, 0.84 mmol) and azetidine hydrochloride (75 mg, 0.8 mmol) in DMF (5 mL) and the mixture stirred at RT for 72 hours. Ethyl acetate (40 mL) was added and washed with water (2×30 mL), brine (30 mL), dried (MgSO4), filtered and reduced in vacuo to give a yellow oil which was chromatographed on silica, eluting with 0-100% ethyl acetate in isohexane, to give the desired compound (48 mg).
