反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 1.4 g (0.006 mole) of 3,4-dihydro-6-(alpha,alpha-dihydroxy-acetyl)-quinolin-2-(1H)-one and 1.37 g (0.008 mole) of 1,1-dimethyl-3-phenyl-propanamine in 60 ml of ethanol and 30 ml of dimethylformamide is heated to 80° C. for 2 hours and, after cooling to room temperature, about 1.5 g of sodium borohydride are gradually added. After 2 hours, the mixture is acidified with acetic acid and the solvent is evaporated off in vacuo. After being rendered alkaline with 2N sodium hydroxide solution, the residue is extracted with methylene chloride. The residue of the organic phase is purified by column chromatography on silica gel (CHCl3 /MeOH 93/7). the solvent is evaporated off in vacuo the residue is extracted with methylene chloride The residue of the organic phase is purified by column chromatography on silica gel (CHCl3 /MeOH 93/7)

実験手順: To 1,1-dimethyl-3-phenylpropylamine (3.6 g., 22 mmole) in 20 ml. 2-propanol at 50° C. in an oil bath was added glycidol (1.7 g., 23 mmole) in 10 ml. 2-propanol dropwise over 5-10 min. The mixture was heated at 75° C. for 2 hours. After evaporation of the solvent, vacuum distillation provided 3.9 g. (75%) of 3-(1,1-dimethyl-3-phenylpropylamino)-1,2-dihydroxypropane (bp 160°-180°/0.5 mm which crystallized upon standing (mp 74°-77° C.). After evaporation of the solvent, vacuum distillation provided 3.9 g (75%) of 3-(1,1-dimethyl-3-phenylpropylamino)-1,2-dihydroxypropane (bp 160°-180°/0.5 mm which crystallized
