Procedure

To a solution of 594 mg of tert-butyl (S)-[[1-(2-[[(1-amino-6-isoquinolinyl)carbonyl]amino]-1-oxopropyl)piperidin-4-yl]oxy]acetic acid in 8 mL of dioxane was added 3 mL 36% hydrochloric acid and stirred at room temperature for two hours. The solution was concentrated and trituration of the residue with diethyl ether yielded 560 mg of the title compound. HPLC Supelcosil LC-18-DB column using a gradient elution system of 20% A/80% B to 20% A/20% B/60% C over 40 min at a flow of 0.25 ml/min (A: 0.5M phosphate buffer pH 2.1, B: water, C acetonitril/water 3/2 v/v). Rt=22.4 min.
