Procedure

A solution of tert-butyl 3-(4-(6-chloropyrimidine-4-carboxamido)-3-methylphenylsulfonamido)propanoate (Intermediate 34, 140 mg; 0.31 mmol) and diisopropylamine (105.5 mL; 0.61 mmol) in ethanol (4 ml) was treated with N-(cyclopropylmethyl)cyclohexanamine (56.6 mg, 0.4 mmol). The mixture was heated to 160° C. in a microwave for 1 hour and the solvent reduced to one tenth of the volume in vacuo. The solid formed was triturated with water and the residue purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc to give tert-butyl 3-(4-(6-(cyclohexyl(cyclopropylmethyl)amino)pyrimidine-4-carboxamido)-3-methylphenylsulfonamido)propanoate which was used directly without any further purification. The residue was redissolved in DCM (4.5 ml) and treated with TFA (0.5 ml). After stirring at RT for 2 hours the solvent was removed in vacuo to give the title compound as an off-white solid.
