To a solution of the product of example 13, step (a) (4.2 g) and diisopropylethylamine (1.2 ml) in dioxan (40 ml) was added bromoacetonitrile (1.2 g) and the mixture heated at 100° C. for 23 hours. After cooling, the red reaction solution was adsorbed onto silica and purified by silica gel flash column chromatography, eluting with dichloromethane then 95:5 dichloromethane:ethyl acetate, to give the subtitled compound as a pale orange solid (3.1 g).
