Reaction Steps
A procedure analogous to that used for 1a was used with the following materials: 2,2'-(phenylimino)diethanol (9.0 g, 50 mmol), t-butyldimethylsilyl chloride (18.1 g, 0.12 mol), imidazole (17.0 g, 0.25 mol), and dimethylformamide (50 mL). The reaction was stirred overnight for convenience. Workup as in 1a gave 3a as a pale oil (21.6 g, >100%). 1H NMR (CDCl3) δ7.21 (2H, d, J=8.4), 6.68 (3H, overlapping d, t), 3.77 (4H, d, J=6.6), 3.52 (4H, d, J=6.6), 0.92 (18H, s), 0.06 (12H, s). 13C NMR (CDCl3) δ147.8, 129.2, 115.7, 111.4, 60.3, 53.5, 25.9, 18.3, -5.3. FDMS (m/e) 409 (M+). It was used as 100% without purification.
