Vorschrift

5-Benzoyl-6-(bromomethyl)-1,3-dimethyl-1H-pyrimidine-2,4-dione (Intermediate A step 3) (200 mg 0.59 mmol), triethylamine (82 μl, 0.59 mmol) and (R)-2-aminopropan-1-ol (45 mg, 0.59 mmol) (commercial) were combined in EtOH (2 mL). The mixture was heated at 100° C. under microwave irradiation for 1 hour. The solvent was evaporated under reduced pressure. The solid residue dissolved in DCM and water and extracted (×3). The combined organic phases were washed with water, passed through a hydrophobic frit and evaporated under reduced pressure to afford the title compound as an off-white solid.
