Procedure

A solution of 9-bromo-1-nonanol (0.446 g) in MeCN (3.9 mL) was added to solution of (2-isopropylthiazol-5-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone (example 114, step b) (0.395 g) and triethylamine (0.36 mL) in MeCN (8.6 mL). The resulting mixture was stirred at 60° C. under argon for 16 h. After cooling to RT the solvent was removed in vacuo. The residue was taken up in DCM (25 mL), washed with brine (20 mL) and water (20 mL), dried over sodium sulphate, filtered and evaporated in vacuo. The residue was purified by silica gel chromatography eluting with 0-10% MeOH in DCM to give the subtitled compound as a white solid. Yield 0.329 g.
