실험 절차

(3R,4S)-4-(6-(tert-butyl)imidazo[1,2-a]pyridin-2-yl)-1-(tert-butyldimethylsilyl)-3-methylazetidin-2-one (Preparation 40) was dissolved in THF and 1 M tetrabutylammonium fluoride in THF (3 mL, 10 mmol) was added. The reaction mixture was stirred for 2 hours then the solvent was removed in vacuo. The intermediate was purified by silica gel column chromatography eluting with 0-100% CMA80 in dichloromethane to afford the title compound.
