Procedure

Benzyltrimethylammonium hydroxide (40% in water, 0.27 mL) was added in one portion to a stirred solution of (9-(2-(5-(2-hydroxyethyl)thiophen-3-yl)ethyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(2-isopropylthiazol-4-yl)methanone [Example 78, step b] (0.92 g) and tert-butyl acrylate (0.38 g) in toluene (1 mL). The resultant mixture was stirred vigorously at 20° C. for 4 hours. Acetonitrile (1 mL) was added and the mixture was stirred for 18 hours and then purified without work up. The crude product was purified by flash silica chromatography, using 6% methanol in ethyl acetate with 1% triethylamine as solvent. Fractions containing the product were evaporated to dryness to afford the subtitled compound. Yield 0.84 g.
