Embodiment 1
[0049] The solid phase synthesis method of embodiment 1 HS-20001
[0050] (1) Drying and swelling of solid phase synthetic resin
[0051] Weigh 50g (20mmol) of Fmoc-Lys(Mtt)-HMPA-AM resin (0.4mmol / g) which was vacuum-dried for 24 hours and place it in a 2L bubbler bottle, add 500mL N,N-dimethylformamide (DMF) Swell the resin for 30 minutes, then remove the DMF solution;
[0052] (2) Fmoc-Lys(Mtt)-HMPA-AM resin removes 4-methyltrityl (Mtt) protecting group
[0053] Wash the resin with 200mL DCM, repeat once, add 1200mL 1% TFA / DCM (TFA about 8 times excess) to remove the Mtt protecting group, reaction time 30 minutes, use 200mL 5% N, N-diisopropylethylamine (DIEA) / DMF and DMF were washed 3 times, and DMF was washed three times.
[0054] (3) Condensation of palmitic acid
[0055] Weigh 50mmol each of palmitic acid and 3-(diethoxyphosphoryloxy)-1,2,3-benzotriazin-4-one (DEPBT), add 400mL DMF to dissolve, then add 100mmol DIEA and stir the reaction at room temperature After 3...
Embodiment 2
[0070] The solid phase synthesis method of embodiment 2 HS-20002
[0071] (1) Drying and swelling of solid phase synthetic resin
