Reaction Steps

To the title compound of step A (319 mg, 0.89 mmol) in DCM (8.7 mL) was added 4M HCl in dioxane (1.1 mL). The reaction was allowed to proceed overnight then concentrated and neutralized with 5% Na2CO3 (aq) and extracted with DCM (2×). The combined organics were dried (Na2SO4) to give the title compound of step B that was used without further purification.
