Reaction Steps

To a suspension of {1-[2-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propionyl]piperidin-4-yl}carbamic acid tert-butyl ester (EXAMPLE 230, 500 mg, 0.92 mmol) in methanol (12 mL) was added a solution of 4M HCl in dioxane (0.69 mL, 2.76 mmol) and the reaction stirred for 48 h. The resulting precipitate was filtered and washed with ethyl acetate to give the title compound as the hydrochloride salt as a pale yellow powder. m/z (ES+)=444.16 [M+H]+; RT=2.65 min. The product was dissolved in saturated sodium bicarbonate solution. Solvent was removed in vacuo and the crude material dissolved in THF (30 mL). The solution was filtered through celite and solvent removed in vacuo to give the title compound as a yellow powder. m/z (ES+)=444.32 [M+H]+; RT=2.59 min.
