反応手順

0.43 g of sodium hydride (60% in oil) was suspended in 10 ml of tetrahydrofuran, and 1.0 g of methyl N-methoxycarbamate and 1.36 g of propargyl bromide were added to the suspension in this order while being cooled with ice. The mixture was heat-refluxed for 4 hours. After completion of the reaction, water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was dried, concentrated and purified by silica gel column chromatography to obtain 0.8 g of methyl N-methoxy-N-propargylcarbamate.
