Reaction Steps

A suspension of 2-(pivaloylamino)-pyrrolo[2,3-d]pyrimidine and ZnCl2 (3-20 equiv.) in wet EtOH (5 vol % water) was heated to 80 AC, and monitored by HPLC. When the reaction reached completion, DCM was added, and the organic layer was washed with sat. aq. NaHCO3 and brine. Drying (Na2SO4) and concentration afforded the desired 2-amino-pyrrolo[2,3-d]pyrimidine.
