Ergosterol (5.00 g, 12.6 mmol) was dissolved in dichloromethane (100 mL), and pyridine (4 mL) and acetyl chloride (2 mL) were sequentially added at 0° C. thereto, followed by stirring at room temperature for 18 hours. The reaction mixture was concentrated to yield a residue and then methanol was added to the obtained residue for trituration to obtain the title compound (5.21 g, 94%).
