EXAMPLE 39 Preparation of The titled compound was synthesised using 4-pentanoylpyridine as the starting material following the procedures described in Example 1, except that 3-fluorophenylhydrazine was substituted for 4-fluorophenylhydrazine. 4-Butanoylpyridine and 4-pentanoylpyridine both can be synthesised according to procedures described by J. L. Born and S. Early in J. Pharm. Sci., vol. 69, pp. 850-851, (1980). m.p. 93-94 C. Anal. Calc'd. for C17H16FN3: C, 72.58; H, 5.73; N, 14.94. Found: C, 72.44; H, 5.81; N, 14.67. |

27% | With pyridinium chlorochromate; In dichloromethane; for 2.0h; | n-Propyl 4-pyridyl ketone. Pyridinium chlorochromate (4.27 g, 19.84 mmol) was suspended in dry dichloromethane (50 mi) in a round-bottom flask under an atmosphere of N2. After stirring for 5 min, 1-(4-pyridyl)-1-butanol (2.0 g, 13.23 mmol) in dry dichloromethane (10 ml) was added. The reaction was followed by t. l. c. and once complete (-2 h) anhydrous ether (70 ml) was added. The supernatant was decanted and the residual black gum was washed with anhydrous ether (4x100 ml). The combined organic fractions were concentrated in vacuo, and the black tar-like substance was purified by flash chromatography [EtOAc as eluant] to give a brown oil. The product was then purified by silica gel column chromatography [3: 1 EtOAc: hexanes as eluant] to give n-propyl 4-pyridyl ketone [Registry No. 1701-71-9] as a yellowy-green oil (520 mg, 27%).
