YieldReaction ConditionsOperation in experiment
99%
Stage #1: With potassium carbonate In toluene at 148℃; for 21 h; Heating / reflux
Stage #2: With hydrogenchloride In water
Stage #3: With sodium hydroxide In water
(R)-N-methyl-3-(2-methylphenoxy)-benzenepropanamine hydrochloride:; A 3 -necked 100 ml glass reactor was flushed for 15 min with N2 and subsequently charged with 15 g (90.8 mmol) of the above mentioned (3R)-methyl-3-hydroxy-3- phenylpropylamine (>99 percent ee, chiral HPLC), potassium phosphate (28.9 g, 136.2 mmol) and 1.73 g copper(I)iodide (9.8 mmol, 10 mol-percent). 60 ml of toluene was added to the mixture and the suspension was stirred for 5 min. 12.8 ml (100 mmol) of 2-iodotoluene was added and the reaction mixture was heated to reflux for 24 h. After cooling to room temperature, the suspension was filtered and the filter cake was washed with 60 ml of toluene. 75 ml of water was added to the filtrate and the mixture was stirred for 10 min at room temperature. The aqueous phase was brought to pH 1-2 with 30 percent HCl and the phases were separated. 60 ml of toluene was added to the aqueous phase and aqueous NaOH was added until pH 12-14 of the aqueous phase was reached. After stirring for EPO <DP n="16"/>10 min the phases were separated. The organic phase was evaporated under reduced pressure yielding 25 g of an oil.The oil was redissolved in 80 ml of toluene, warmed to 80 °C and 36 g of a 10 percent HCl- ethyl acetate solution was added dropwise to the solution. During cooling of the solution a white solid precipitated. After 5 h at room temperature, the suspension was filtered and the residue was dried in vacuum at about 50 °C to yield 22 g (75.4 mmol, 83 percent) of (R)- N-methyl-3-(2-methylphenoxy)-benzenepropanamine hydrochloride.The (R)-N-methyl-3-(2-methylphenoxy)-benzenepropanamine hydrochloride salt was placed in a 100 ml reaction vessel and 55 ml of isopropanol was added. Upon heating to reflux temperature all solids were dissolved. Slow cooling to room temperature gave 18.1 g (82 percent) of colorless (R)-N-methyl-3-(2-methylphenoxy)-benzenepropanamine hydrochloride (>99 percent ee, HPLC).
