Reaction Steps

Monomethylamine, (22.43 kg, 722.15 mol, 6 eq.) was added over a 7-hour period to a solution of methyl-4-hydroxyphenylacetate (20.0 kg, 120.35 mol, 1.0 eq.) in methanol (31.7 gal, 120 L) and stirred overnight at room temperature. Methanol was then displaced under vacuum with ethyl acetate. The resulting slurry (about 20 gal, 75.7 L) was stirred at +10° C. for 1 hour, then filtered and dred under vacuum at 45° C. to yield the title compound(18.68 kg, 94% of theory).
