To a stirred solution of 2-chloronicotinic acid (8.00 g, 51.0 mmol) in THF (120 mL) at 0° C. under nitrogen was slowly added lithium tetrahydroaluminate (51 mL, 51 mmol) over five minutes. The reaction was allowed to warm to RT over 2 h and was monitored by TLC. The reaction was quenched by addition of small amounts of ice followed by water. Extracted product into EtOAc, washed 2×H2O , 1×NaCl, dried with Mg2SO4, filtered through fritted funnel, and concentrated the solution to yield (2-chloropyridin-3-yl)methanol as an orange oil. Used without further purification.
