(4-Chloro-3-pyridinyl)methanol

To a solution of 4-chloro-nicotinic acid ethyl ester (1.5 g, 8.1 mmol) in ether (15 mL) was added lithium aluminum hydride (0.31 g, 8.2 mmol) in ether (10 mL) over 10 min while cooling. The reaction mixture was stirred for 1 h and quenched with water (2 mL) and 15percent NaOH (0.5 mL). The reaction mixture was filtered and the residue on the filter was washed with ether. The combined filtrate was dried over anhydrous Na2SO4 and concentrated in vacuo to afford 0.75 g of (4-chloro-pyridin-3-yl)-MeOH as a yellowish solid.Example 5 4-chloro-3-hydroxymethylpyridine To a solution of 4-chloro-3-pyridyl carboxyaldehyde (140 mg, 1.0 mmol) in THF (1 mL) at 0° C. was added methanol (1 mL) followed by portionwise addition of sodium borohydride (75 mg, 2.0 mmol). After 1 hr, acetic acid (0.15 ml) was added and the reaction mixture was evaporated to dryness with rotary evaporator at room temperature. The solid residue was chromatographed on silica gel column (1percent MeOH/dichloromethane) to afford 60 mg (42percent) of the title compound. 1H NMR (CDCl3) delta4.30 (br s, 1H), 4.80 (s, 2H), 7.30 (d, 1H, J=5), 8.34 (d, 1H, J=5), 8.62 (s, 1H).Example 5 4-chloro-3-hydroxymethylpyridine To a solution of 4-chloro-3-pyridyl carboxyaldehyde (140 mg, 1.0 mmol) in THF (1 mL) at 0° C. was added methanol (1mL) followed by portionwise addition of sodium borohydride (75 mg, 2.0 mmol).
