실험 절차

To the title compound of Example 19, Step A (1.3 mmol, 407 mg) in DMF (5 mL) was added NaH (1.6 mmol, 62 mg of 60% suspension in mineral oil). After 10 min methyl-4-(bromomethyl)benzoate (1.3 mmol, 304 mg) was added and the reaction mixture was allowed to stand at ambient temperature for 2 h. Aqueous workup with CH2Cl2/saturated NaHCO3 and brine, followed by flash chromatography on silica eluting with 40%, 50% and 60% EtOAc in hexanes afforded the product as a tan solid. LC-MS (ESI, Method B): 1.93 min, m/z 456.1 (M+1).
