반응 단계
TBAF (1M solution in THF, 2 mL) was added to a solution of benzo[b]thiophen-2-yl(9-(3-(2-(tert-butyldimethylsilyloxy)ethyl)-2-fluorobenzyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone (example 79, step a) (0.370 g) in THF (4 mL). After 0.5 h, the solution was concentrated. Purification by silica gel chromatography eluting with 10:1 ethyl acetate:triethylamine gave the subtitled compound as a gum. Yield 0.26 g.
