Yield:-
Reaction Conditions:
with triethylamine in dichloromethane at 20; for 18 h;
Steps:
1
To a solution of (3-Aza-bicyclo[3.1.0]hex-6-yl)-methanol-HCl (11.8 gm, 78.7 mmol) in 350 mL of anhydrous CH2Cl2 at room temperature was added Et3N (32.9 mL, 236 mmol), followed by (BOC)2O (18.9 gm, 86.6 mmol) in portions. The reaction was stirred at room temperature for 18 hours. The mixture was washed with saturated NaHCO3, water, brine and dried over anhydrous MgSO4. The mixture was filtered and concentrated under reduced pressure to yield the crude material, which was purified via flash chromatography with 10% MeOH/CH2Cl2. The product containing fractions were collected and concentrated to yield 6-Hydroxymethyl-3-aza-bicyclo[3.1.0]hexane-3-carboxylic acid tert-butyl ester (15.6 gm). 400 MHz 1H NMR (CDCl3) δ 3.4-3.6 (m, 4H), 3.2-3.7 (m, 2H), 1.72 (brs, 1H), 1.4-1.4 (m, 10H), 0.9-0.9 (m, 1H); MS (M+1) 213.2.
