Procedure
5.12 g (60% yield) was prepared by the method of Example 19G from 5.5 g 3-(4-t-butyldimethylsilyloxymethylphenyl)-4-fluoroaniline and 3.5 ml diethyl ethoxymethylenemalonate. A pale yellow-green oil was obtained. NMR (CDCl3, 250 MHz): 8.5 (d, 1H, J=12 Hz), 7.5 (ABq, 4H), 7.2 (m, 3H), 4.8 (s, 2H), 4.25 (m, 4H), 1.35 (m, 6H), 1.0 (s, 9H), 0.1 (s, 6H).
