実験手順
1-[(1S)-2-(Benzyloxy)-1-({[tert-butyl(dimethyl)silyl]oxy}methyl)ethyl]-2-(chloromethyl)-1H-imidazo[4,5-c]quinoline (1.61 g, 3.13 mmol) was dissolved in 250 mL of anhydrous CH2Cl2 and the solution was cooled to −78° C. under N2. A 1.0 M solution of tetrabutylammonium fluoride in THF (3.43 mL, 3.43 mmol) was added and the stirred solution was allowed to warm to ambient temperature overnight. The reaction mixture was then washed successively with 50 mL of saturated NaHCO3 solution and brine (4×50 mL). The organic portion was dried over Na2SO4, filtered and concentrated under reduced pressure. Chromatography (SiO2, 0-3% methanol/CHCl3) gave 0.92 g of (11S)-11-[(benzyloxy)methyl]-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinoline as a colorless syrup.
