Procedure

To a solution of Example 9 (42 mg, 0.095 mmol) in DMF (1 mL), was added diiosopropylethylamine (33 μL, 0.19 mmol) followed by HATU (72 mg, 0.19 mmol). After 1 hour, N,N-dimethylpropanolamine (67 μL, 0.57 mmol) was added, and the reaction mixture was stirred at 60° C. for 16 hours. The reaction mixture was allowed to cool to RT then partitioned between EtOAc and water. The organic layer was separated, and the aqueous layer further extracted with EtOAc. The combined organic layers were washed with brine, dried (Na2SO4) and evaporated in vacuo. The resulting residue was purified by silica gel chromatography eluting with a gradient of 0-6% (2 M NH3 in MeOH) in DCM to give the title compound as a white solid (15 mg).
