Reaction Steps

A solution of 3-(3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)propyl)thiazolidine-2,4-dione (0.20 g, 0.43 mmol), cyclopropanecarbaldehyde (91 mg, 1.3 mmol, 3.0 eq.) and a drop of piperidine in ethanol (15 mL) was refluxed overnight. The volatile phase was removed under reduced pressure. The residue was applied on silica gel and eluted with petroleum:ethyl acetate (3:2) to give 3-(3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)propyl)-5-(cyclopropylmethylene thiazolidine-2,4-dione (50 mg) as a white solid. MS (ESI, pos. ion) m/z: 513 (M+1)
