Phenylacetic-p-arsinic acid, C02H.CH2.CgH4.As0(0H)2. This is obtained by applying the Bart reaction to p-aminophenylacetic acid, the resulting arsinic acid melting at 195° C- Neutralisation by alkali and heating with sodium hydrosulphite yields an carseno-dmvative, which dissolves in sodium carbonate.

Benzyl-l(2/i/)-phthalazmone (44) underwent Mannich aminoalkylation by p-aminophenylacetic acid and formaldehyde to give 4-benzyl-2-[p-(carboxy-methyl)anilinomethyl]-l(2fl)-phthalazinone (45) (reactants, H2O, MeOH, reflux, 30 min then 20°C, 12 h 70% analogs likewise). 

Knowledge of the biosynthesis of PABA remains about where B. D. Davis left it in his studies of aromatic biosynthesis. A possible intermediate between shikimic acid and PABA may be p-aminophenylacetic acid, which... 

This has been examined using Acetobacter suhoxydans and Cl. acetobulyl-icum, and the results (Table XVIII) for these organisms are in substantial agreement. There are some discrepancies in the observations recorded for Cl. acetobutylicum with a few of the compounds. Rubbo and Gillespie (324) reported that p-aminophenylacetic acid was 10 times more active than p-aminobenzoic acid, but other observers have failed to confirm this (183, 456). Lampen and Peterson (183) found that the apparent activity of commercial p-aminophenylacetic acid fell from 0.1% of the potency of p-aminobenzoic acid to 0.002%, after two recrystallizations. Rubbo and Gillespie (324) and Landy and Wyeno (197) noted that p-aminophenylace-...
