Yield: 97%

Reaction Conditions:

with triethylamine in dichloromethane at 23;

Steps:

1.3.3.1 Step 1: Eth vi 1 -((tert-butoxycarbonyl )am ino)cyclopropanecarboxylate
To a solution of ethyl 1-aminocyclopropanecarboxylate hydrochloride (3.22 g, 19.4 mmol) in DCM (35 mL) was added triethylamine (2.71 mL, 19.4 mmol) upon which a suspension was obtained. A solution of Boc2O (4.24 g, 19.4 mmol) in DCM (5 mL) was added dropwise over ca. 2 mm. The reaction mixturewas stirred at RT overnight. Aqueous I M KHSO4 (100 mL) and DCM (50 mL) were added. The organic layer was separated, dried (Na2SO4), evaporated under reduced pressure and co-evaporated with THF (2x), to afford 4.31 g (97%) of the desired product.
