Compound 65 (0.336 g, 1.00 mmol) was dissolved in PhNO2 (7 mL). The solution was cooled down in an ice bath. Then, AlCl3 (0.67 g, 5.02 mmol) and after that, AcCl (0.36 mL, 5.04 mmol) were added. The resulting mixture was kept for 40 min (LC/MS monitoring), diluted with water, neutralized with aqueous NaHCO3 solution, extracted with CHCl3, and evaporated. The product was purified on a short thick column, eluent: 100:0→90:10. Yield of product: 0.307 g (82%) (R); S-isomer was obtained similarly (77%).
