実験手順

(3-Bromo-propyl)-carbamic acid tert-butyl ester (11.2 g, 47.0 mmol) was combined with 2.0 M Methylamine in THF (100 mL, 200 mmol) and was stirred at room temperature for 4 h. After this period, a precipitate formed in the solution. The solution was filtered and concentrated under reduced pressure to yield 7.58 g (86%) of (3-methylamino-propyl)-carbamic acid tert-butyl ester as a clear oil. [M+H]+ 188.94.
