실험 절차

A solution of 2-(5-(bromomethyl)-2-fluorophenyl)ethanol [Aromatic Intermediate 2] (5.17 g) in ethanol (20 mL) was added dropwise to a suspension of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate [Example 1, step b] (9.4 g) and potassium carbonate (6.75 g) in ethanol (75 mL) and the resulting mixture stirred overnight. The mixture was filtered, the filter cake was washed with ethanol (50 mL), and the filtrate and washings combined and evaporated. The residue was partitioned between water (100 mL) and ethyl acetate (250 mL). The phases were separated and the organic phase washed with brine (100 mL), dried over sodium sulphate, filtered and evaporated. The residue was purified by flash silica chromatography using 95:5 ethyl acetate:triethylamine as solvent to give the subtitled compound as a clear oil. Yield 7.9 g.
