Synthesis of 2amino1hydroxyphenylethanol

[Vibrating_Lights]

IN the reduction of the nitroalcohol.... to get a Proper isomer to use in an DL-amiorex synth,  Would it be best to use EtOH with 37%Formaldahyde and activated zinc to reduce the nitro group?
 Is AN acid nescesary to complete the reduction?

IS an equimolar ammount of Formaldehyde used or a catalyctic ammount?

Then how would one get a halogen at the 4 position on the oxilone ring where the phenyl group is position 5,  without halogenating the phenyl ring.
