Reaction Steps

To an 8 mL vial charged with 2-methoxyacetyl chloride (6.6 mg, 0.061 mmol) was added (R)-1-(3-amino-1-trityl-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-(1-phenylethyl)urea (30 mg, 0.056 mmol) in DCM (1 ml) and pyridine (0.045 ml, 0.557 mmol). The vial was capped and the contents stirred at room temperature for 16 h. The reaction mixture was diluted with DCM (1 mL), MP-Trisamine (137 mg, 0.278 mmol) added, and the contents of the vial shaken at room temperature for 3 h. The resin was filtered, and washed through with DCM (1 mL). The volatiles were removed in vacuo to afford crude (R)-2-methoxy-N-(6-(3-(1-phenylethyl)ureido)-1-trityl-1H-pyrazolo[4,3-c]pyridin-3-yl)acetamide, which was taken forward without purification. MS ESI calc'd. For C37H35N6O3 [M+H]+ 611. found 611.
