실험 절차

A mixture of Example 27B (13.5 g, 85 mmol) and 4,4-dimethyl-3-oxopentanenitrile (11.69 g, 93 mmol) in ethanol (50 mL) was refluxed at 90° C. for 6 hours. The mixture was concentrated under reduced pressure and ethyl acetate (20mL) added to the residue. The white solid precipitate was filtered, washed with ether and dried to yield 17.5 g (90%) of title compound as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.42-0.54 (m, 4H), 1.16-1.27 (m, 1H), 1.28 (s, 9H), 4.02 (d, J=7.12 Hz, 2H), 5.53 (s, 1H), 6.91 (s, 2H), 14.05 (s, 1H); H); MS (DCI) m/z 294 [M+H]+.
