Yield	Reaction Conditions	Operation in experiment
100%	at 20℃; for 18 h;	A 3-necked, 5 L round-bottomed flask was equipped with a mechanical stirrer, a J-KEM temperature probe, and a N₂ inlet adapter connected to a bubbler. The round-bottomed flask was charged with glycine benzyl ester hydrochloride (505.2 g, 2.51 mol, 1.0 equiv.) and CH₂Cl₂ (3.0 L). The milky, white reaction mixture was treated with benzophenone imine (471.1 g, 97percent, 2.6 mol, 1.00 equiv.) and an exotherm (+4.5° C.) was observed. The reaction mixture stirred at 20° C. for 3 h and TLC (50percent ethyl acetate/heptane) showed a trace of starting material. Additional benzophenone imine (25.0 g, 0.14 mol) was added to the reaction mixture and the mixture was stirred for 15 h at 20° C. TLC confirmed reaction completion. This mixture was filtered through a short pad of Celite to remove ammonium chloride, and the filter cake was rinsed with CH₂Cl₂ (1.5 L). The filtrates were concentrated in vacuo to produce a white solid that was dried in vacuo to give the desired crude product: 878.7 g (106percent); ¹H-NMR(DMSO-d₆): 7.53-7.25 (m, 13H), 7.12 (dd, 2H), 5.10 (s, 2H), and 4.17 (s, 2H).

65%	Stage #1: 4-phthalimidobenzoic acid With O-(1H-benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate; triethylamine In N,N-dimethyl-formamide at 20℃; for 0.166667h; Stage #2: benzyl 2-aminoacetate hydrochloride In N,N-dimethyl-formamide for 24h;	General Procedure for the Synthesis of Benzyl Esters 5a and 5b General procedure: A round bottom flask was charged with 4 (534 mg, 2 mmol), dry DMF (10 mL), TEA (0.557 mL, 4 mmol), and HBTU (796 mg, 2.1 mmol). After stirring at rt for 0 min., 2.1 mmol of benzyl ester of glycine or L-phenylalanine hydrochloride were added, and the reaction mixture was stirred for 1 day in the case of 5a and 4 days in the case of glycine derivative 5b. To the reaction mixture brine (50 mL) was added and extraction with diethyl ether was carried out (1×50 mL). The product in a form of colourless solid was suspended between the organic and aqueous layers. After removal of the aqueous layer, the suspension of solid in ether was washed with 1M HCl (50 mL), H2O (50 mL), saturated aqueous NaHCO3 (50 mL), and again with H2O (50mL). The suspension was filtered through a sinter (D-4) and the solid product was dried in a vacuum oven at 60°C and 10 mbar to afford the pure products.

The reaction mixture was concentrated and residue was purified by column chromatography on 40 g SiO2 ISCO column, eluting with 100% Hexanes (2 column volumes); then 0-100% EtOAc in Hexanes (6 column volumes), 100% EtOAc (6 column volumes) to give the title material as an oil. UPLC-MS Method B, Rt = 3.13 min, m/z = 444.0 [M+1].
