Versuchsvorschrift

A solution of 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-5-fluorophenyl)ethanol (example 55, step c) (0.153 g) in DMF (7 mL) was treated with triethylamine (0.208 mL) followed by 2-isopropylthiazole-5-carboxylic acid (example 55, step b) (0.085 g). The mixture was cooled to 0° C. and HATU (0.245 g) was added. The reaction mixture was stirred for 2 hours at 20° C. The mixture was partitioned between ethyl acetate and brine, the organic layer was washed twice with brine, dried over sodium sulphate, filtered and the solvent evaporated under reduced pressure. The crude product was purified by flash silica chromatography using 2.5% methanol in dichloromethane with 1% triethylamine as solvent. Pure fractions were evaporated to dryness to afford the subtitled compound. Yield 0.130 g.
