Versuchsvorschrift

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.25 g) was added to a solution of 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-5-fluorophenyl)ethanol (example 55, step c) (0.16 g), 2-propylthiazole-4-carboxylic acid (example 56, step c) (0.09 g) and triethylamine (0.29 mL) in DMF (7 mL) and the resulting yellow solution was stirred for 30 min. The mixture was partitioned between ethyl acetate (100 mL) and brine (100 mL). The organic phase was separated, washed with brine (2×100 mL), dried over sodium sulphate, filtered and the solvent evaporated. The resulting gum was purified by silica gel chromatography eluting with 47.5:47.5:5 isohexane:ethyl acetate:triethylamine to 95:5 ethyl acetate:triethylamine gradient. The fractions containing product were combined, toluene (200 mL) was added, and the mixture evaporated to give the subtitled compound as a clear gum. Yield 0.14 g.
