Procedure

A solution of Methyl 2-{[(benzyloxy)carbonyl]amino}-3-(7-chloro-4-{[(4-methoxybenzyl)amino]methyl}-1H-indazol-5-yl)propanoate from Step A in toluene (100 mL) was heated at reflux for 3 hours and then cooled to room temperature. The reaction mix was poured into a saturated aqueous solution of sodium bicarbonate and the mixture was extracted with Ethyl acetate (2×200 mL). The combined organic extracts were washed once with brine (100 mL), dried over anhydrous sodium sulfate, filtered and concentrated at reduced pressure. The resulting solid was swished once with a 1:1 mix of ethylacetate/hexane and the solid collected by filtration to give 3.1 g of the title compound to give the title compound. MS: m/z 505 (M+1).
