Reaktionsschritte

HATU (0.209 g) was added to a stirred solution of 5-ethylthiophene-3-carboxylic acid (0.086 g), 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)phenyl)ethanol (example 82, step a) (0.160 g), and triethylamine (0.3 mL) in DMF (2 mL). After 1 h, the reaction mixture was diluted with ethyl acetate (25 mL) and washed with brine (2×25 mL). The ethyl acetate layer was evaporated in vacuo. Purification by silica gel chromatography eluting with 10:1, ethyl acetate:triethylamine gave the subtitled compound as a gum. Yield 0.18 g.
