Procedure

1-Chloro-N,N,2-trimethyl-1-propenylamine (2.67 mL, 20 mmol) was added to a solution of 3-{[6-(azetidin-1-ylcarbonyl)pyridin-3-yl]oxy}-5-[(phenylmethyl)oxy]benzoic acid (6.18 g, 15.3 mmol) in DCM (100 mL) and the reaction stirred at RT for 50 mins. 2-Amino-5-methylpyrazine (3.34 g, 30.6 mmol) and pyridine (2.5 mL, 30.6 mmol) were added and the reaction stirred overnight. The solvent was removed in vacuo, and the residue taken up in ethyl acetate (350 mL). The organic phase was washed with water (2×100 mL), brine (100 mL), dried (MgSO4), filtered, and evaporated in vacuo. The residue was chromatographed on silica, eluting with a gradient of 50-75% ethyl acetate in isohexane, to give the desired material (4.01 g). 1H NMR δ (CDCl3): 2.28 (quin, 2H), 2.49 (s, 3H), 4.18 (t, 2H), 4.63 (t, 2H), 5.05 (s, 2H), 6.78 (s, 1H), 7.10 (s, 1H), 7.25-7.37 (m, 7H), 8.04 (d, 1H), 8.07 (s, 1H), 8.25 (s, 2H), 9.46 (s, 1H); m/z 496 (M+H)+
