Yield	Reaction Conditions	Operation in experiment
		2-Chlorotritylchloride resin (1.22 mmol/g, 0.87 g, 1 mmol) was weighted into a 10 ml syringe with fit. The resin was swollen with 5 mL DCM and washed with DCM (5x4 mL). N-FmocL-Asp(OtBu)-OH (1.1 g, 2.7 mmol) was dissolved in DCM (5 mL) and DIPEA (0.66 mL,3.78 mmol) was added and the solution drawn into the syringe. The syringe was agitated for 1 h. MeOH (0.5 mL) was drawn into the syringe and the syringe agitated for 15 mm. The resin was washed 5 times with DCM (4 mL) and 5 times with DMF (5 mL). The resin was agitated 3 times for 5 mm with DMF:DBU:piperidine (96:2:2 v/v/v 4 mL). The resin was washed 5 times with DMF (4 mL). Acetic anhydride (0.51 mL, 5.4 mmol) and DIPEA (1.9 mL, 10.8mmol) were dissolved in DMF (6 mL) and the solution was drawn into the syringe and the syringe agitated for 15 mm. The resin was washed 5 times with DMF (4 mL), 5 times with DCM (4 mL). A solution of HFIP/DCM (1/4 v/v, 5 mL each) were drawn into the syringe and the syringe agitated 3 times for 10 mm. The collected filtrates were concentrated in vacuo. Crude 18e (0.29 g, 1.23 mmol, 114 %) was used without further purification in the next step.MS: m/z 254.38= [M+Na], (calculated = 254.12).
