With triethylamine In dichloromethane at 0 - 20℃; for 2h; 9.4; 12.4 Step 4: Into a lOO-mL 3-necked round-bottom flask, was placed (2R)-morpholin-2-ylmethanol hydrochloride (0.70 g, 4.56 mmol, 1.00 equiv), DCM (20.00 mL), and Et3N (1.84 g, 18.23 mmol, 4.00 equiv). This was followed by the addition of 3-ethoxy-2-formylbenzoyl chloride (1.07 g, 5.03 mmol, 1.10 equiv), in portions at 0 ?C. The resulting solution was stirred for 2 h at room temperature. The reaction was then quenched by the addition of 20 mL of water. The resulting solution was extracted with 3 x 20 mL of dichloromethane, and the organic layers were combined and dried over anhydrous sodium sulfate and concentrated. The residue was applied onto a silica gel column with THF/PE (50%). This resulted in 2-ethoxy-6-[(2R)-2-(hydroxymethyl)morpholine-4-carbonyl]benzaldehyde.

After the addition was complete, the mixture was stirred at RT. The reaction was monitored by LCMS. After stirring at RT for 1 h, the reaction was finished to afford a solution. After concentration in vacuo, the residue was purified by reversed phase HPLC on a GILSON 281 instrument fitted with a Phenomenex Synergi C18150x30mmx4um column using water (0.1% TFA)-ACN as eluents (Mobile phase A water (0.1% TFA), Mobile phase B ACN, Detective wavelength 220 nm) and concentration to give the title compound as a solid. 1H NMR (400 MHz, CD3OD) d 7.43 - 7.54 (m, 2 H), 7.28 - 7.36 (m, 1 H), 4.95 - 5.17 (m, 2 H), 4.41 - 4.67 (m, 3 H), 3.86 - 4.12 (m, 2 H), 3.48 - 3.67 (m, 4 H), 3.33 (br d, J=4.4 Hz, 1 H), 3.20 - 3.27 (m, 1 H), 2.72 - 3.29 (m, 5 H), 2.48 (s, 3 H), 2.15 (br s, 2 H), 1.82 (br d, J=8.4 Hz, 2 H), 1.55 - 1.77 (m, 2 H), 1.07 - 1.19 (m, 1 H), 0.28 - 0.36 (m, 1 H); MS (ESI) m/z: 547.3[M+H+].

96.99% With sodium carbonate In 1,4-dioxane; water at 0 - 10℃; for 12h; 20 To a solution of Fmoc-Cl (47.16 g, 182.28 mmol) in dioxane (600 mL) was added Na2CO3 (57.96 g, 546.85 mmol) in H2O (500 mL), followed by compound 1R (28 g, 182.28 mmol) in dioxane (600 mL) added dropwise at 0-5 °C, then the mixture was stirred at 5 - 10 °C for 12 hrs. LCMS showed desired MS was detected. TLC showed the reaction was completed, staring material was consumed. The mixture was diluted with H2O (500 mL) and extracted with EtOAc (500 mL*4), the combined organic layers were dried over Na2SO4, filtered and concentrated under reduced pressure to give a residue. The residue was purified by column chromatography (SiO2, Petroleum ether/Ethyl acetate=1/0 to 0/1). Compound 2R (60 g, 96.99% yield) was obtained as a white oil. LCMS: M+H+ = 340.1. TLC (Petroleum ether : Ethyl acetate = 0:1 ) Rf= 0.32.
