실험 절차

1-Chloro-N,N,2-trimethyl-1-propenylamine (0.11 mL, 0.80 mmol) was added to a solution of 3-{[6-(azetidin-1-ylcarbonyl)pyridin-3-yl]oxy}-5-[((1S)-2-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}-1-methylethyl)oxy]benzoic acid (0.3 g, 0.62 mmol) in DCM (10 mL) and stirred for 1 hour. 2-Amino-5-methylpyrazine (135 mg, 1.23 mmol), then pyridine (0.1 mL, 1.23 mmol), were added and the mixture stirred for a further 30 mins before being reduced in vacuo and partitioned between ethyl acetate (50 mL) and water (50 mL). The aqueous layer was further extracted into ethyl acetate (50 mL) and the combined organics washed with water (50 mL), brine (50 mL), dried (MgSO4), filtered and reduced in vacuo. The crude oil was chromatographed on silica, eluting with 40-100% ethyl acetate in isohexane, to give the desired compound as a colourless oil (82 mg).
