Ammonia → 2-(3-(1-Oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-5-fluorophenyl)ethanol

Participants

Reaction Steps

‘880’ Ammonia solution (5 mL) was added to a solution of 2,2,2-trifluoro-1-(9-(3-fluoro-5-(2-hydroxyethyl)benzyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)ethanone (example 41, step d) (2.2 g) in methanol (25 mL). The resulting mixture was stirred for 90 min and the solvent evaporated. The residue was azeotroped three times with acetonitrile and concentrated to give the subtitled compound as a clear gum. Yield 1.96 g.
