Versuchsvorschrift
2-Chloro-6-((2S,6R)-4-methanesulfonyl-2,6-dimethyl-piperazin-1-ylmethyl)-7-methyl-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (135 mg, 0.29 mmol) was reacted with 2-amino-pyrimidine-5-boronic acid pinacol ester (88 mg, 0.4 mmol) in General Procedure A. After extraction into 2M HCl, the mixture was washed with ethyl acetate then made basic and the precipitate collected by filtration. Purification using a thiourea SPE cartridge gave 420 as a cream solid (90 mg, 0.17 mmol) NMR (CDCl3, 400 MHz), 9.25 (s, 2H); 5.12 (s, 2H); 3.95 (t, 4H, J=4.6 Hz); 3.95 (s, 2H); 3.82 (t, 4H, J=4.8 Hz); 3.51 (d, 2H, J=11.3 Hz); 2.82 (m, 2H); 2.74 (s, 3H); 2.55 (t, 2H, J=10.8 Hz); 2.33 (s, 3H); 1.06 (d, 6H, J=6.3 Hz) MS: (ESI+): MH+=533.30
