Procedure

A solution of 6-((cyclopropylmethyl)(propyl)amino)-N-(1H-indazol-5-yl)pyrimidine-4-carboxamide (Example 45, 350 mg; 1 mmol) in DMF (4 ml) was treated with potassium carbonate (140 mg; 1 mmol), and ethyl 2-bromoacetate (184 mg; 1.1 mmol). After stirring at RT for 18 hours the mixture was poured into water (20 ml) and stirred at RT for 30 minutes. The solid was removed by filtration and purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc to give the title compound as an off-white solid, together with ethyl {5-[({6-[(cyclopropylmethyl)(propyl)amino]pyrimidin-4-yl}carbonyl)amino]-2H-indazol-2-yl}acetate (Example 120 below).
