5synthesis methods
-

Yield:57561-39-4 100%

Reaction Conditions:

in dichloromethane at 20; for 1 h;

Steps:

8.1 Step 1:
To a solution of 2-(methylamino)ethanol (500 mg, 0.53 ml, 6.66 mmol) in CH2Cl2 (20 ml) was added Boc2O (1.48 g, 6.79 mmol), followed by stirring at room temperature for 1 hour. The reaction solution was extracted with brine and CH2Cl2. The organic layer thus obtained was dried over MgSO4 and filtered. Then, the filtrate was concentrated in vacuo to obtain the object compound (colorless oil, quantitative); 1H NMR (200 MHz, CDCl3) δ 3.74 (q, J= 10.5, 5.2 Hz, 2H) 3.25 (t, J= 5.2 Hz, 2H) 2.91 (s, 3H) 1.45 (s, 9H); mass spectrum m/e (relative intensity) 144 (20) 102 (24) 57 (70) 44 (100).
