Reaction Conditions

Reaction Steps

To a solution of compound 282 (280 mg, 1 eq.) in dry EtOH (6 mL) was added compound 291 (1.38 g, 5 eq.) under nitrogen, followed by NaOEt (165 mg, 1 eq.). The reaction mixture was stirred at 90° C. for 2 hrs. EtOH was evaporated and a DCM/water mixture was added. Aqueous layer was acidified to pH 5 with aqueous 1N HCl and was extracted with DCM. The combined organic layers were dried over Na2SO4, filtered, concentrated in vacuo, and purified by chromatography on silica gel (DCM/MeOH) to yield compound AI1 as a beige oil in 81% yield. MS (ESI, EI+): m/z=340 (MH+).
