Reaction Steps

90% Formic acid (5.5 mL) is added to a suspension of 4-cyclopentyloxy-5-methoxy-2-trityloxypyridine (1.2 g) in ethyl acetate (8.5 mL) and the mixture stirred at room temperature for 1 hours. The mixture is diluted with ethyl acetate and washed with brine then aqueous sodium bicarbonate until the washings are neutral. The brine washings are neutralised with solid sodium bicarbonate and extracted with ethyl acetate. After drying (MgSO4) the extracts are evaporated to give 4-cyclopentyloxy-2-hydroxymethyl-5-methoxypyridine (360 mg) as a white solid, m.p. 93-94.5° C. [Elemental analysis: C, 64.7; H, 7.80; N, 6.11%. calculated: C, 64.55; H, 7.68; N, 6.27%.].
