Reaction Steps

{1-[7-(4-Bromo-2,6-dimethylphenyl)-2,5-dimethyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl]piperidin-4-yl}methanol (1.15 g) synthesized in the similar manner as example 1 in tetrahydrofuran (25 mL) was stirred, then NaH (60% in paraffin, 0.10 g) was added and the mixture was heated at reflux for 3 hours. After cooling to 0° C., ethyl chloroformate (0.28 g) in a small amount of tetrahydrofuran was added and the reaction mixture was allowed to reach room temperature and evaporated. The residue was purified over a silica gel on a glass filter (eluent: CH2Cl2/CH3CN=95:5 then 90:10) to give the title product (366 mg).
