실험 절차

tert-Butyl (R)-2-(tert-butyldimethylsilyloxy)-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethyl((R)-1-(3-formylphenyl)propan-2-yl)carbamate (Example 276, step i) (0.476 g) was treated with (5-isopropylthiophen-3-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone (Example 275, step i) (0.296 g), N-methyl-2-pyrrolidinone (20 mL), acetic acid (0.052 mL) and sodium triacetoxyborohydride (0.294 g), and the mixture was stirred at room temperature overnight. The solution was poured into a mixture of saturated sodium bicarbonate solution and water and extracted three times with diethyl ether. The combined extracts were washed with water and brine, dried (MgSO4) and concentrated in vacuo, then purified by flash chromatography on silica eluted with 1:5:94 NEt3:MeOH:DCM to afford the subtitled compound. Yield 0.471 g.
