実験手順

A solution of 2.39 g (6.43 mmol) of 10-hexyl-3,7-dimethoxy-phenothiazine-4-carbaldehyde in 30 ml of tetrahydrofuran was reduced with 7.0 ml of lithium borohydride solution (1M in tetrahydrofuran) analogously to that described in Example 4.1.1.da. The resulting 10-hexyl-3,7-dimethoxy-phenothiazine-4-methanol was reacted with 4.0 ml of n-butyllithium solution (1.6M in hexane) and 1.0 g (8.0 mmol) of 2-methoxyethoxymethyl chloride analogously to that described in Example 4.1.1.db. After chromatography on silica gel with diethyl ether/hexane (3:2) 2.33 g (78.5%) of 10-hexyl-3,7-dimethoxy-4-(2-methoxy-ethoxymethoxymethyl)-phenothiazine were obtained as a light yellowish oil.
