Reaction Steps

A mixture of N-methyl-N-[(3R,4R)-4-methylpiperidin-3-yl]-N-(1H-pyrrolo [2,3-b]pyridin-4-yl)-amine (43.0 mg, 0.000176 mol) and 3-[(2,5-dioxopyrrolidin-1-yl)oxy]-3-oxopropanenitrile (38 mg, 0.00021 mol) in ethanol (1 mL, 0.02 mol) was stirred overnight. The reaction mixture was partitioned between ethyl acetate/THF and sat. NaHCO3, and the organic layer was washed by sat. NaCl. The solvent was removed under vacuum to give 100 mg of an orange solid which was chromatographed with 7% MeOH/DCM, 0.7% NH4OH to give 17 mg of pale orange solid. The crude product was triturated with Et2O and the resulting solid was filtered and washed to give 9.4 mg of wet pale orange solid which was dried at from room temperature to about 60° C. for 3.5 h to give 6.5 mg of the final product.
