The white foam isolated from the 1:9 and 1:4 benzene-hexane elutes is crystallized from hexane to provide 4.38 g. base. A 300 mg. portion is crystallized (twice) from hexane thereby yielding 200 mg. of title compound, m.p. 117°-119°C., NMR (CDCl3): δ 2.45 (singlet, 3-methyl), 5.70 (triplet, J 8 cps., 7-hydrogen) ppm.
