The production process of 5-(Hydroxymethyl)-3-pyridinecarbonitrile can be broadly classified into the following steps:

1. Preparation of Pyrrole-3-carboxaldehyde
   The first step in the production of 5-(Hydroxymethyl)-3-pyridinecarbonitrile is the preparation of Pyrrole-3-carboxaldehyde.
   This is done by reacting Pyrrole with Formaldehyde in the presence of a solvent, such as water or methanol.
   The reaction is exothermic and proceeds via a sequential mechanism.
   
2. Condensation of Pyrrole-3-carboxaldehyde with Methylamine
   The second step involves the condensation of Pyrrole-3-carboxaldehyde with Methylamine in the presence of an acid catalyst, such as Sulfuric acid.
   The reaction takes place at high temperatures and pressures and yields N-(3-Pyridylmethyl)amine.
   
3. Reduction of N-(3-Pyridylmethyl)amine
   The next step is the reduction of N-(3-Pyridylmethyl)amine to produce N-(3-Pyridyl)methylamine.
   This is done by treating N-(3-Pyridylmethyl)amine with Hydrogen in the presence of a catalyst, such as Palladium on barium oxide.
   
4. Condensation of N-(3-Pyridyl)methylamine with Phenylisocyanate
   The next step involves the condensation of N-(3-Pyridyl)methylamine with Phenylisocyanate in the presence of a solvent, such as Benzene or Toluene.
   The reaction is catalyzed by a Lewis acid, such as Aluminum chloride.
   The reaction generates a large amount of heat and can be exothermic.
   
5. Reduction of N-(5-Hydroxymethyl-3-pyridine-1,2-dione)
   The final step is the reduction of N-(5-Hydroxymethyl-3-pyridine-1,2-dione) to produce 5-(Hydroxymethyl)-3-pyridinecarbonitrile.
   This is done by treating N-(5-Hydroxymethyl-3-pyridine-1,2-dione) with Hydrogen in the presence of a catalyst, such as Raney Nickel.
