Temperature: 60 °C

Procedure

A mixture of tert-butyl {2-[4-({3-chloro-4-[3-(trifluoromethoxy)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethyl}carbamate (173 mg), 2N hydrochloric acid (2.5 mL) and tetrahydrofuran (5.0 mL) was stirred at 60° C. for 6 hrs. Ethanol was added to the reaction system. The solvent was evaporated under reduced pressure. Ethanol was added to the concentrate, and the mixture was further concentrated under reduced pressure. The residual crystals were collected by filtration and the crystals were washed with ethyl acetate to give the title compound (155 mg) as pale-yellow crystals.
