Quinaldine zinc complexes

A number of improvements have been made in these syntheses. For example, the use of ethanoHc ferric chloride and zinc chloride produces a good yield of 2-isopropylquinoline [17507-24-3] from isovaleraldehyde (46). The purification of 2-methylquinoline is facHitated through precipitation. A cmde quinaldine—hydrochloride and zinc chloride complex is prepared and then treated with aqueous base (47). [Pg.391]

Methylquinoline (quinaldine) [91-63-4] M 143.2, b 86-87"/lmm, 155"/14mm, 246-247"/760mm, d4 1.058, n D 1.6126, p 5.65. Dry it with Na2S04 or by refluxing with BaO, then fractionally distil it under reduced pressure and redistil it from zinc dust. Purify it further by conversion to its phosphate (m 220°) or picrate (m 192°) from which after recrystallisation, the free base is regenerated. [Packer et al. JAm Chem Soc 80 905 1958.] Its ZnCl2 complex can be used for the same purpose. [Beilstein 20 III/IV 3454, 20 V 375.]... [Pg.462]
