Procedure

HATU (0.201 g) was added in one portion to a stirred solution at 0° C. of 3-(3-(2-(8-(2-isopropylthiazole-4-carbonyl)-5-oxa-2,8-diazaspiro[3.5]nonan-2-yl)ethyl)phenethoxy)propanoic acid trifluoroacetate salt (0.25 g) (example 176 step b), N-ethyl-2,2-dimethoxyethanamine (0.059 g) (U.S. Pat. No. 2,707,186) and triethylamine (0.283 ml) in DMF (4 mL). The mixture was stirred at 20° C. for 3 hours and then partitioned between ethyl acetate and aq brine, the organic layer was washed with brine (×2), dried, filtered and the solvent evaporated under reduced pressure to afford the subtitled compound. Yield 0.250 g.
