Reaction Steps

5-(4-Amino-3-methoxyphenyl)-7-tetrahydro-2H-4-pyranyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (50 mg, 0.147 mmol) was dissolved in dichloromethane (1.5 mL). Pyridine (1.5 mL) was added followed by 2,2-dimethylpropanoyl chloride (31 mg, 0.221 mmol). After stirring at room temperature for 2 hours, the solvent was removed and the residue was dissolved in 1 ml DMSO, methanol (1 mL) was added and precipitate was formed. The solid was collected by filtration to give N1-[4-(4-amino-7-tetrahydro-2H-4-pyranyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methoxyphenyl]-2,2-dimethylpropanamide (27 mg, 0.064 mmol). 1H NMR (CDCl3-d) δ 1.35 (s, 9H), 2.09 (m, 4H), 3.66 (m, 2H), 3.96 (s, 3H), 4.13(m, 2H), 4.97 (m, 1H), 5.46(bs, 2H), 6.98 (s, 1H), 7.04 (s, 1H), 7.07 (d, J=8.2 Hz, 1H), 8.15 (s, 1H), 8.29 (s, 1H), 8.49 (d, J=8.2 Hz, 1H). LC/MS: MH+=424.
