YieldReaction ConditionsOperation in experiment
18.6 kg (36.6mol) 3-dimethylamino propyl triphenylporphyrin phosphorus hydrobromide and 90L non-water mixing and stirring THF, under the protection of nitrogen, is added in batches 3.18 kg (79.8mol) NaH, temperature control 20-40°C, after adding, the temperature rising to 50-60°C, reaction 4h, then adding 3 kg (11.4mol) intermediate (III), stirring the mixture at room temperature for overnight, cooling to 0-15°C, slowly adding 60L water, using ethyl acetate (30L × 3) extraction. PH=8 for adjusting the HCl aqueous phase, the n-butanol extraction product (12L × 2), with an organic layer 6L a water washing, concentrating under reduced pressure nearly dry, add 12L ethyl acetate stirring 1h, filtering, to obtain 2.36 kg intermediate IV (Z/E = 65.12/32 . 82), yield: 62.5percent.
