Reaction Conditions:
with thionyl chloride in tetrahydrofuran at 20; for 0.5 h;
Steps:
1.b
Thionyl chloride (12.4mL, 170mmol) was added to a 1L round bottom flask containing tetrahydrofuran (500mL). The flask was cooled in an ice-water bath and a solution of (2- aminopyridin-3-yl) methanol (17. 6g, 142mmol) in tetrahydrofuran (150mL) was added dropwise at a rate such that the temperature remained below 10°C. The reaction mixture was warmed to room temperature and stirred for an additional 30 minutes. The solvent was evaporated and the residual solid was ground to a fine powder with a mortar and pestle, then dried under vacuum to give 23.2g (92%) of the title compound as a yellow powder.'H NMR (CDC13) 8 4.63 (s, 2H), 6.87 (m, 1H), 7.58 (br s, 2H), 7.85 (m, 2H).
