Reaction Steps

130 μl (0.69 mmol) of 2,6-diisopropylaniline are added to a solution of 180 mg (0.65 mmol) of (1-phenyl-1,3-diazaspiro[4.5]dec-3-yl)acetic acid in 20 ml of dichloromethane. The solution is cooled to −10° C. and 132 mg (0.69 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide are added. The medium is allowed to return to room temperature and stirred for 4 h and then at reflux for one day and again at room temperature for 5 days. The medium is then poured into water and extracted with dichloromethane. The organic phases are collected and washed with water. They are dried over sodium sulfate. The solvents are evaporated. The residue is chromatographed on silica gel (heptane/ethyl acetate 90/10, v/v). 25 mg of N-(2,6-diisopropylphenyl)-2-(1-phenyl-1,3-diazaspiro[4.5]dec-3-yl)acetamide are obtained in the form of a white solid. M.p. 151-3° C., yield=8.8%.
