Here is a downstream synthesis route of the compound 5187-23-5.

Example 12: Synthesis of Tetradecafluoro-di(propylamino)- phthalocyaninatocobalt(II), Dodecafluoro-tetrapyrrolidino-phthalocyaninatocobalt(II) and MONO- (5-ETHYL-1, 3-DIOXANE-5-METHYLOXY)-HEXAFLUORO-TETRANEOPENTOXY-PENTAPYRROLIDIYAO- phthalocyaninatocobalt (II) [00129] FI6COPC (40 mg) was dissolved in 1 ml of propylamine and stirred for 10 min. Then the amine was evaporated and an aliquot was taken for MALDI-MS. It shows substitution of 1-6 fluorines by propylamine. To the remaining solid 1 ml of pyrrolidine was added and the suspension was stirred at room temperature for 5 min. After that the pyrrolidine was evaporated and an aliquot was taken for MALDI-MS. It shows substitution of 3-4 fluorines by pyrrolidine but no more products with propylamine as the substituent. To the remaining solid 1 ml of diisopropylamine was added and the mixture was heated to 80C for 4 hrs. The amine was evaporated and an aliquot taken for MALDI-MS. It shows substitution of 3-5 fluorines by pyrrolidine. There is no evidence that diisopropylamine has reacted with the Pc. To the remaining solid (dark blue green) was added a mixture of 0.93 ml nBuLi and 328 mg neopentylalcohol. The mixture was stirred at 110C for 90 min. Since the suspension almost solidified, some 5-ethyl-1, 3-dioxane-5-methanol was added and heated to 140C for 1 h. The colour turned from green to brown. But after cooling down it was green again. So another 328 mg neopentylalcohol were added and heated to 140C for 90 min. The colour turned brown again. The mixture was purified by silica gel chromatography with ethylacetate/hexanes (1: 1) as the eluent. An olive green and a green fraction were taken and submitted for MALDI-MS. Two peaks among several could be identified: [00130] 1) fluorines were replaced by 5 pyrrolidines and 4 neopentylalcohols [00131] 2) the same as above with an 5-ethyl-1, 3-dioxane-5-methanoxy. [00132] The reaction schemes for the synthesis of the various products of this example are provided in Figure 7.
