Participants

Reaction Steps

1-Chloro-N,N,2-trimethyl-1-propenylamine (0.042 mL, 0.31 mmol) was added to a solution of 3-{[5-(azetidin-1-ylcarbonyl)pyrazin-2-yl]oxy}-5-{[(1R)-1-methyl-2-(methyloxy)ethyl]oxy}benzoic acid (0.102 g, 0.0.31 mmol) in DCM (3 mL) under argon and stirred at RT for 40 minutes. 2-Amino-5-methylpyrazine (57 mg, 0.52 mmol) and pyridine (0.043 mL, 0.52 mmol) were added and the reaction stirred for a further 3 hours. The solvent was removed in vacuo and the residue taken up in ethyl acetate (30 mL), washed with water (2×10 mL), a saturated aqueous solution of sodium bicarbonate (10 mL), brine (10 mL), dried (MgSO4), filtered, and evaporated in vacuo. The crude material was chromatographed on silica, eluting with a gradient of 60-100% ethyl acetate in isohexane, to give the desired compound as a white foam (86 mg).
