Procedure
A solution of (4-(methoxymethyl)phenyl)boronic acid (999 mg, 6.02 mmol), glyoxylic acid monohydrate (554 mg, 6.02 mmol) and diallylamine (0.741 mL, 6.02 mmol) in acetonitrile (12 mL) was stirred at 60° C. for 5 hr. The reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (Diol, solvent; ethyl acetate), and crystallized from ethyl acetate/hexane to give 2-(diallylamino)-2-(4-(methoxymethyl)phenyl)acetic acid (200 mg, 0.726 mmol, 12.07%) as crystals.
