以5-甲氧基煙腈為原料合成3-氰基-5-羥基吡啶的一般步驟：將1g 5-甲氧基煙腈（7.46mmol）與8.62g鹽酸吡啶混合，在200℃下加熱反應(yīng)2小時(shí)。反應(yīng)完成后，將粗產(chǎn)物用水稀釋，并用乙醚多次萃取。水相通過(guò)加入碳酸氫鈉進(jìn)行堿化后，再次用乙醚萃取。合并有機(jī)相，經(jīng)無(wú)水硫酸鈉干燥后，減壓濃縮，得到850mg米色固體5-羥基煙腈，收率95%。產(chǎn)物經(jīng)LC-MS分析：m/z 120.94（M+H+）。1H NMR（400MHz, DMSO-d6）：δ 10.79（s, 1H, OH），8.46（s, 1H, Harom.），8.42（s, 1H, Harom.），7.60（s, 1H, Harom.）。
