Versuchsvorschrift

A mixture of (2-methylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 4, step h) (0.244 g), 4-(3-bromopropoxy)benzaldehyde (example 8, step a) (0.15 g) and triethylamine (0.344 mL) in MeCN (2 mL) was heated at 60° C. After 16 h, the reaction mixture was evaporated in vacuo. Purification was by silica gel chromatography eluting with ethyl acetate:triethylamine, 10:1 to give the subtitled compound as an oil. Yield 0.24 g.
