Procedure

The product of Example 14 (1.33 g, 0.002 mol) and triethylamine (1.0 g, 0.01 mol) in dry acetonitrile (25 ml) is stirred as triphenylphosphine (1.15 g, 0.0044 mol) is added in one lot. After stirring for a further 5 minutes, the dye separates, is collected and washed with acetonitrile, to yield 0.34 g (53 %) of crude dye, which is purified by recrystallization from acetonitrile, mp. indistinct.
