実験手順

The procedure of Example 18 was followed starting with 4-chlorobutoxybenzaldehyde (10 g, 47 mmol) and using 2-methylbenzothiazole (6.0 ml, 47 mmol) in place of 2-methylbenzoxazole to give 10.1 g (63% yield) of (E)-2-[2-(4-chlorobutoxyphenyl)ethenyl]benzothiazole (H) as a solid, mp 98°-100° C. 1H NMR (CDCl3): δ 8.01-6.89 (m, 10H), 4.01 (t, J=5.2 Hz, 2H), 3.61 (t, J=5.2 Hz, 2H), 1.94 (m, 4H).
