Reaction Steps

Following the same procedure as described in Example 7, step 1 using 4-Chloro-5,8-dihydro-6H-9-thia-1,3,7-triaza-fluorene-7-carboxylic acid tert-butyl ester (3.5 g, 0.011 mol), 3,4-dichloroaniline (1.9 g, 0.012 mol), 4 N HCl in Dioxane (1.3 ml) in 2-propanol (72 ml) and gave the desired product (3.0 g, 72%). LCMS RT=2.77 min, [M+H]+=351.8.
