Procedure

HATU (1.1 g) was added in one portion to a cooled solution of 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-yl)methyl)-4-fluorophenyl)ethanol [Example 44, step c] (0.7 g) and 2-isopropylthiazole-4-carboxylic acid (0.39 g) and triethylamine (0.95 mL) in DMF (15 mL). The reaction mixture was stirred at 20° C. for 1 hour and then partitioned between ethyl acetate and brine. The organic layer was washed with brine (×2), dried, filtered and the solvent removed under reduced pressure. The crude product was purified by flash silica chromatography, using 3% methanol in ethyl acetate containing 1% triethylamine as solvent. Fractions containing the product were evaporated to dryness to afford the subtitled compound. Yield 0.61 g.
