Reaction Conditions

Reaction Steps

A 300-mL portion of the filtrate described above, containing 1.26 M 3-cyanopentanoic acid ammonium salt, was adjusted to pH 2.5 with ca. 60 mL of 6 N HCl, then saturated with sodium chloride and extracted with 4×200 mL of ethyl ether. The combined organic extracts were dried over magnesium sulfate, filtered, and the solvent removed by rotary evaporation at reduced pressure at 28° C. The resulting slightly-yellow viscous oil was stirred under high vacuum (50 millitorr) to remove residual solvent at 28° C., then cooled to -20° C. for 2-3 h to produce 3-cyanopentanoic acid as a crystalline white solid (45.9 g, 96% yield); m.p. 33.0-34.0° C.
