Reaction Steps
To a solution of ethyl 2-chloronicotinate (1 g, 5.39 mmol) in 10 ml EtOH at room temperature is added 2.04 g (53.9 mmol) NaBH4 over 30 minutes in several portions. The solution is stirred for. The excess borohydride is quenched by the addition of methanol. The solvents are evaporated and the residue partitioned between dichloromethane and water. The aqueous Phase is extracted 3× with 10 ml of dichloromethane. The combined organic layers are washed with brine, dried with MgSO4, filtered and evaporated in vacuo to yield a light yellow oil.
