실험 절차

A solution of 5-(tert-butyloxycarbonyl)-2-(4-fluorobenzyl)-8-hydroxy-6-methyl-2,3,4,4a,5,6-hexahydro-2,6-naphthyridine-1,7-dione, Diastereomer 1 from Example 4, (0.015 g, 0.037 mmol) in 50% TFA in CH2Cl2 (2.4 mL) was stirred at room temperature. After 1.3 hours, TFA acid (0.5 mL) was added to the reaction mixture. After 48 hours, the reaction mixture was concentrated under vacuum to give the title compound. ES MS M+1=349.
