---|---|---|
25% | Stage #1: With hydrogenchloride; sodium nitrite In water at -5℃; for 0.25 h; Stage #2: With potassium hydroxide; sodium acetate In ethanol; water at 0℃; for 18 h; Stage #3: With toluene-4-sulfonic acid In toluene at 110℃; for 5 h; |
7.2 g (0.104 mol) of sodium nitrite dissolved in 40 ml of water are added, at 5 C., to a mixture of 10.7 g (0.1 mol) of 4-methylaniline, 74 ml of 12 N hydrochloric acid and 140 ml of water. The reaction mixture is stirred for 15 minutes at 5 C. and is neutralized by addition of 8.1 g of sodium acetate. 12.33 g (0.085 mol) of ethyl a-methyl acetoacetate and 80 ml of ethanol are introduced into a three-necked Uask, followed, at 0 C., by 4.8 g (0.085 mol) ofpotassium hydroxide dissolved in 20ml ofwater and 100 g of ice. The diazonium solution prepared above is added dropwise, at 0 C., to this reaction mixture and the resulting mixture is left for 18 hours at 0 C. The aqueous phase is extracted 4 times with 50 ml of ethyl acetate and the organic phases are combined and dried over anhydrous sodium sulphate. The residue is taken up in 100 ml of toluene and 16.3 g (0.085 mol) of para-toluene sulphonic acid monohy drate. The mixture is then heated slowly to 110 C. and maintained at this temperature for S hours. After cooling and then addition of saturated sodium carbonate solution, the insoluble material is removed by ltration and the organic phase is separated out after settling has taken place, dried over anhydrous sodium sulphate and concentrated. The residue is chromatographed on a column of silica gel, eluent:30/70 (v/v) dichloromethane/cyclohexane, to give beige coloured crystals; m.p.=94 C.; yield=25percent. |
