Procedure

1-Chloro-N,N,2-trimethyl-1-propenylamine (0.080 mL, 0.6 mmol) was added to a solution of 3-{[5-(azetidin-1-ylcarbonyl)pyrazin-2-yl]oxy}-5-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}benzoic acid (193 mg, 0.50 mmol) in DCM (10 mL) and stirred at RT for 30 minutes. 2-Aminopyridine (57 mg, 0.6 mmol) and pyridine (0.082 mL, 1 mmol) were added and the reaction stirred for a further 16 hours. The solvent was removed in vacuo and the residue was taken up in ethyl acetate (50 mL). The organic phase was washed with water (2×20 mL), 1N citric acid (10 mL), water (10 mL), a saturated aqueous solution of sodium bicarbonate (10 mL) and brine (100 mL), then dried (MgSO4), filtered, and evaporated in vacuo. The residue was chromatographed on silica, eluting with a gradient of 50-80% ethyl acetate in isohexane, to give the desired compound as a white foam (42 mg). 1H NMR δ (CDCl3): 1.28 (d, 3H), 2.31 (quin, 2H), 3.34 (s, 3H), 3.43-3.56 (m, 2H), 4.19 (t, 2H), 4.57 (q, 1H), 4.62 (t, 2H), 6.90 (s, 1H), 7.03 (t, 1H), 7.20 (s, 1H), 7.36 (s, 1H), 7.71 (t, 1H), 8.23 (d, 1H), 8.28 (s, 1H), 8.30 (d, 1H), 8.64 (s, 1H), 8.79 (s, 1H); m/z 464 (M+H)+
