Compound 25 was prepared using a method similar to that described for 23. The o reagents used were as follows, compound 17 (25.5 g, 0.172 mol.), compound 19 (91.5 g, 0.336 mol.), sodium hydride (60% by wt. in mineral oil (14.0 g, 0.350 mol.). The final product was a colorless liquid (30.0 g 60%) (bpt. 100°-120 0° C., 0.06 torr.): 1H-NMR (CDCl3), d (ppm) 3.8-3.4 (m, 17H), 1.55 (m, 4H, CH2), 1.2 (s, 9H, C(CH3)3), 0.9 (t, 6H, --CH3).
