Reaction sequence:

Glucose + C_6H_5NHNH_2 \;\;\xrightarrow{-H_2O}\;\; CH=NNHC_6H_5

$Glucose$ $+$ $C$ $6$ $$ $H$ $5$ $$ $NHNH$ $2$ $$ $-$ $H$ $2$ $$ $O$ $$ $CH$ $=$ $NNHC$ $6$ $$ $H$ $5$ $$ $\;\;\;\;\; | \\ \;\;\; CHOH \\ \;\;\; (CHOH)_3 \\ \;\;\; CH_2OH$ $∣$ $CHOH$ $($ $CHOH$ $)$ $3$ $$ $CH$ $2$ $$ $OH$ $\;\;\xrightarrow[{ -C_6H_5NH_2, NH_3 }]{ C_6H_5NHNH_2 }$ $C$ $6$ $$ $H$ $5$ $$ $NHNH$ $2$ $$ $-$ $C$ $6$ $$ $H$ $5$ $$ $NH$ $2$ $$ $,$ $NH$ $3$ $$ $$

CH=NNHC_6H_5 \;\;\; | \\ C=O \\ (CHOH)_3 \\ CH_2OH \;\;\xrightarrow{ C_6H_5NHNH_2 }

$CH$ $=$ $NNHC$ $6$ $$ $H$ $5$ $$ $∣$ $C$ $=$ $O$ $($ $CHOH$ $)$ $3$ $$ $CH$ $2$ $$ $OH$ $C$ $6$ $$ $H$ $5$ $$ $NHNH$ $2$ $$ $$ $CH=NNHC_6H_5 \;\;\; | \\ C=NNHC_6H_5 + H_2O \\ (CHOH)_3 \\ CH_2OH$ $CH$ $=$ $NNHC$ $6$ $$ $H$ $5$ $$ $∣$ $C$ $=$ $NNHC$ $6$ $$ $H$ $5$ $$ $+$ $H$ $2$ $$ $O$ $($ $CHOH$ $)$ $3$ $$ $CH$ $2$ $$ $OH$
