Yield:89105-35-1 89%

Reaction Conditions:

with thionyl chloride at 0 - 20; for 16 h;Inert atmosphere;

Steps:

5.3 Step 3: (S)-Ethyl 2-aminopent-4-enoate (S5)

[0476] To a solution of Scheme 5-7 compound S4 (5 g, 43.5 mmol) in EtOH (70 mL) was added SOCI2 (15.52 g, 130.5 mmol) dropwisely at 0 °C. The reaction was stirred at room temperature for 16 h and concentrated. The residue was triturated with Et20 (60 mL) and filtered to afford the title compound (7 g, yield 89 %) as a white powder, which was directly used in the next reaction without further purification. LC/MS (ESI) m/z: 144 (M+H)+.
