Procedure

(2-Isopropyl-thiazol-4-yl)-(1-oxa-4,9-diaza-spiro[5.5]undec-4-yl)-methanone (0.262 g) (prepared from the trifluoroacetate salt as in Example 102, step c) was dissolved in acetonitrile (4 mL) and triethylamine (0.22 mL) was added. This solution was then added to a solution of 7,7-dimethyl-9-oxononyl methanesulfonate (Example 279, step e) (0.291 g) in acetonitrile (4 mL) and the resultant mixture heated at 80° C. overnight. The solvents were removed under vacuum. Purification was by silica gel chromatography eluting with 0-10% Methanol in DCM to afford the subtitled compound as a colourless oil. Yield 0.361 g.
