Versuchsvorschrift

A solution of 9-bromo-1-nonanol (0.346 g) in MeCN (3 mL) was added to solution of (2-phenylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone (example 112, step b) (0.355 g) and triethylamine (0.288 mL) in MeCN (7 mL). The resulting mixture was stirred at 60° C. under argon for 17 h. After cooling to RT the solvent was removed in vacuo. The residue was taken up in DCM, washed with brine (×2), dried over sodium sulphate, filtered and evaporated in vacuo. The yellow oil was purified by silica gel chromatography eluting with 0-7% MeOH in DCM to give the subtitled compound as a white solid. Yield 0.378 g.
