Reaction Conditions

Temperature	20 °C

Reaction Steps

HATU (0.23 g) was added in one portion to an ice cold solution of 3-(4-(2-(4-(2-isopropylthiazole-4-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecan-9-yl)ethyl)phenethoxy)propanoic acid [Example 1, step e] (0.3 g) and N-(2,2-dimethoxyethyl)cyclohexanamine [WO 2008075025] (0.087 g) and triethylamine (0.26 mL) in DMF (10 mL). The mixture was stirred at 20° C. for 1 hour before being partitioned between ethyl acetate and brine. The organic layer was washed with brine (×2), dried, filtered and the solvent evaporated under reduced pressure to afford the subtitled compound. Yield 0.32 g.
