Participants

Reaction Steps

A solution of N-(3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-2,2-dimethylpropyl)-2-cyanoacetamide (0.12 g, 0.26 mmol, 1.0 eq.), cyclopropanecarbaldehyde (56 mg, 0.78 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 eluting with petroleum:ethyl acetate (1:1). This provided 50 mg (38%) of the title compound as a white solid. MS (ESI, pos. ion) m/z: 508 (M+1) H-NMR (300 MHz, DMSO-d6, ppm): 8.59 (t, 1H), 8.29 (s, 1H), 7.69-7.66 (d, J=9.6 Hz, 2H), 7.46-7.41 (t, J=6.6, 7.5 Hz, 2H), 721-7.11 (m, 5H), 7.05-7.02 (d, 10.4 Hz, 1H), 4.18 (s, 2H), 3.04-3.02 (d, J=6.3 Hz, 2H), 1.98-1.93 (m, 1H), 1.21-1.26 (m, 2H), 1.0˜0.92 (m, 2H), 0.91 (s, 6H).
