Reaction Steps

The resulting N-Boc-N-methyl amino butanol (4.00 g) was placed in a 200-mL threeneck flask, and after nitrogen substitution, the compound was dissolved in 35 mL of anhydrous tetrahydrofuran. The solution was added with 60% sodium hydride (1.77 g), and stirred at room temperature for 30 minutes. Then, the reaction mixture was added dropwise with 1.87 mL of methyl iodide and stirred on an oil bath at 50° C. for 1.5 hours. The reaction was stopped with water, and the organic layer was extracted with ethyl acetate, washed once with water and once with saturated brine, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=1/4) to obtain 4.25 g of N-Boc-N-methyl-N-methoxybutylamine.
