Reaction Steps

In a separate reaction vessel, a mixture of sodium hydroxide (0.603 Kg) and methanol (3.18 Kg) was stirred until the sodium hydroxide was completely dissolved and then N-methyl-N-(2-[4-hydroxyphenyl]ethyl) amine HBr salt (A12 HBr) (1 kg, by assay) in methanol (1.58 Kg) was added under an atmosphere of nitrogen. After stirring, the above mixture was concentrated to provide N-methyl-N-(2-[4-hydroxyphenyl]ethyl) amine as a slurry. The solution was cooled to about 5° C. under an atmosphere of nitrogen and then stirred for about 0.5 hours.
