Reaction Steps
This material was prepared in analogy to example 1 step D) from 1-(3-cyclopropyl-propionyl)-4-(2-methoxy-ethyl)-piperidine-4-carboxylic acid ethyl ester (0.1 g), dimethylaluminium chloride in heptane (0.9 molar, 0.71 ml) and 4-trifluoromethoxyanilin (0.057 g) to give the desired 8-(3-cyclopropyl-propionyl)-2-(4-trifluoromethoxy-phenyl)-2,8-diaza-spiro[4.5]decan-1-one (0.021 g) as an off-white solid. MS (ESI): 449.17 (MH+).
