反応手順

To a solution of 2-(2-methoxyethoxyl)ethanamine (0.820 g, 6.88 mmol) in DMF (69 mL) at 0° C. was added dropwise a solution of 1,1′-thiocarbonyldiimidazole (1.349 g, 7.57 mmol) in 21 mL of DMF. The mixture was warmed to RT and stirred for 90 min. The mixture was poured into water (130 mL) and extracted with Et2O (70 mL). The Et2O layer was washed with water, dried over Na2SO4, and filtered. The filtrate was concentrated in vacuo (325 torr, bath temp: 24° C.) to afford 1-isothiocyanato-2-(2-methoxyethoxyl)ethane (0.678 g, 4.21 mmol, 61% yield) as a yellow oil. The crude material was used in next step.
