Reaction Steps

A mixture of 1,1-dimethylethyl N-((4-hydroxy-6-(methyloxy)-2-oxo-2′,3′,5′,6′-tetrahydro-spiro[naphthalene-1,4′-pyran]-3-yl)carbonyl)glycinate (0.66 g, 1.6 mmol) in 3 mL TFA was stirred at room temperature for 30 minutes, M+1=362, M−1=360. The mixture was concentrated and triturated in DCM/heptane (5:10). The solid was filtered, washed with 10 mL DCM/heptane (5:10), and dried under high vacuum to give 0.52 g of the product as a white solid. MS (m/z)=362 (M+H)+. Calculated for C18H19NO7 361.12.
