반응 단계

Isobenzofuran-1,3-dione (4.40 g, 29.76 mmol) and (S)-2-amino-3-phenylpropan-1-ol (4.50 g, 29.76 mmol) were charged into a 20 mL microwave tube along with 10 mL dioxane. The microwave tube was heated at 150° C. for 33 minutes in a Smith Synthesizer. After the reaction was complete, dioxane was evaporated off and the residue was passed through a short pad of silica gel with DCM. The resulting product (7.50 g, 89%) was used in the following step. LCMS (API-ES) m/z (%): 282.2 (100%, M++H).
