Procedure

A mixture of [2-chloro-5-(3,3-diethoxy-prop-1-ynyl)-pyrimidin-4-yl]-cyclopentyl amine (5.21 g, 16 mmol) in THF is added 1M tetra-n-butylammonium floride in THF (TBAF) (97 mL, 97 mmol) and heated to 65° C. for 2 hour. Solvent is removed and column is run using heptane/ethyl acetate from 5% to 15% to give 2-chloro-7-cyclopentyl-6-diethoxymethyl-7H-pyrrolo[2,3-d]pyrimidine (4.26 g, 82%). MS(ESI) m/z 324.5 (M+H)+
