Phenylacetic acid from amino acid w baking soda?

Not sure if I posted this here yesterday but I can't find it if I did and I need opinions/answers... I came up with a possible oxidation of phenylalanine to either phenacetaldehyde or phenylacetic acid with baking soda in water but I'm not sure if it'll work or not... please comment!

Possible oxidation of DL-Phenylalanine to Phenylacetic acid with Sodium Bicarbonate in water

5g of baking soda is dissolved in 500mL of warm water. Once dissolved 2.5g of dl-phenylalanine is added and mixed in until it dissolved. The theoretical phenylacetic acid is either obtained by letting the mixture sit for days (estimated 10-15 days) and let the water evaporate (phenylacetic acid is actually not a liquid, but powder/crystals) or the water can be very carefully boiled off. The yield, if anything is left behind, should be oxidized to phenylacetic acid because phenacetaldehyde is a liquid and so is benzoic acid and benzaldehyde (what you may get with over oxidation, using stronger bases such as NaCL). SO, any powder left would either be unconverted baking soda and phenylalanine mixed together, or our hopes, phenylacetic acid. Some sources are below:
