실험 절차

(+/−)-Benzyl ((1R,3S,5R)-5-(3-((benzoxycarbonyl)amino) pyridin-4-yl)-3-methyl-2-oxocyclohexyl)carbamate (1.0 equiv.) was dissolved in dry THF (0.20 M) under nitrogen and ETHYLENE GLYCOL (8.0 equiv.) was added followed by BF3.OEt2 (1.4 equiv.). The solution was microwave vial and heated at 100° C. for 60 mins. The solution was diluted with EtOAc and washed with sat. sodium bicarbonate, water, brine, dried over sodium sulfate and concentrated. The crude material was purified by ISCO chromatography to afford (+/−)-benzyl ((6R,8R,10S)-8-(3-((benzoxycarbonyl)amino)pyridin-4-yl)-10-methyl-1,4-dioxaspiro[4.5]decan-6-yl)carbamate in 100% yield. LC/MS (m/z)=532.2 (MH+), Rt=0.81 min.
