実験手順

Formic acid (2 mL) was added to stirred solution of (9-(3-(diethoxymethyl)phenethyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(5-methylthiophen-2-yl)methanone (example 20, step e) (0.20 g) in tetrahydrofuran (3 mL) and water (1 mL) cooled in an ice bath. After 10 min, the reaction mixture was evaporated in vacuo, toluene was added and the reaction mixture was evaporated in vacuo. The residue was dissolved in acetonitrile and then evaporated in vacuo, and this process was repeated to give the subtitled compound as an oil that was used directly. Yield 0.16 g.
