실험 절차

A solution of 2,2,2-trifluoro-1-(9-(3-fluoro-5-(2-hydroxyethyl)benzyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)ethanone (example 41, step d) (0.21 g) in methanol (3 mL) was added to ammonia (35% aqueous solution, 15 mL) and the reaction mixture stirred at 20° C. for 1 hour. The mixture was evaporated to dryness under reduced pressure and the residue azeotroped three times with acetonitrile. The residue was dissolved in DMF (7 mL) and treated with 2-isopropylthiazole-4-carboxylic acid (0.098 g) followed by triethylamine (0.290 mL) and then HATU (0.257 g) and the resultant mixture stirred at 20° C. for 1 hour. 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 to afford the subtitled compound. Yield 0.25 g.
