(1S)-2-(4-methylphenyl)-1-phenylethanamine

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

実験手順: An eggplant type flask was charged with 133 mg of potassium cyanide, 1.0 g of (S)-1-phenyl-2-p-tolylethylamine and 1 ml of water. After adding 146 mg of ethyl 1-formylcyclopropane-1-carboxylate dissolved in 2.5 ml of ethanol, dropwise at room temperature, the resulting mixture was further mixed with 0.2 ml of concentrated hydrochloric acid, and stirred for 1 hour at the same temperature and then for 2 hours at 50° C. After confirming completion of the reaction, the reaction solution was mixed with ice water and extracted with ethyl acetate. Next, the resulting organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate and, after removing insoluble matter by filtration, the solvent was evaporated under a reduced pressure. Thereafter, the resulting residue was subjected to a silica gel column chromatography (hexane:ethyl acetate=10:1) to obtain 251 mg (67%) of a diastereomer mixture in the form of colorless oil. Formation ratio of the two diastereomers was found to be 4:1 based on the integral ratio of NMR. for 2 hours at 50° C completion of the reaction extracted with ethyl acetate Next, the resulting organic layer was washed with water and saturated brine dried over anhydrous magnesium sulfate after removing insoluble matter by filtration the solvent was evaporated under a reduced pressure
