実験手順

HATU (0.306 g) was added to stirred solution of 2-tert-butylthiazole-4-carboxylic acid (0.16 g), 9-((4-(2-(tert-butyldimethylsilyloxy)ethyl)thiophen-2-yl)methyl)-1-oxa-4,9-diazaspiro[5.5]undecane (example 43, step b) (0.300 g) and triethylamine (0.41 mL) in DMF (3 mL). After 1 h, the reaction mixture was partitioned between water and ethyl acetate. The ethyl acetate layer was washed twice with water and brine, dried over magnesium sulphate, filtered and evaporated in vacuo. Purification by silica gel chromatography eluting with ethyl acetate:isohexane:triethylamine, 12:90:10 gave the subtitled compound as a gum. Yield 0.3 g.
