실험 절차

To a stirred solution of 35 (117.5 g, 724.48 mmol, 1.00 equiv) in DMF (1.2 L) under N2 was added methoxy(methyl)amine hydrochloride (82.3 g, 844.10 mmol, 1.17 equiv), HATU (329 g, 775.58 mmol, 1.07 equiv), and DIPEA (117.5 mL). The reaction mixture was stirred under N2 at 25° C. overnight and then diluted with water (700 mL). The organic phase was extracted with EtOAc (3×1 L), and the combined organic layers were washed with water (3×1 L) and brine (1×1 L), dried (Na2SO4), filtered and concentrated in vacuo. The residue purified by SiO2 chromatography and eluted with EtOAc/petroleum ether (10 to 50% EtOAc) to afford 62.5 g (42%) of trans-N-methoxy-N-methyl-2-phenylcyclopropane-1-carboxamide (37) as a light yellow oil.
