Procedure

Reaction between (2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-methyl-amine (described above) and 4-formyl-piperidine-1-carboxylic acid tert-butyl ester using standard reductive amination conditions yielded 4-{[(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-methyl-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester, which was reacted with 2-aminopyrimidine-5-boronic acid in General Procedure A, followed by treatment with HCl to cleave the BOC group to yield 320. 400 MHz 1H NMR CDCl3: 9.21 (s, 2H); 7.18 (s, 1H); 5.18 (brs, NH2); 3.96 (t, 4H, J=4.7 HZ); 3.81 (t, 4H, J=4.7 Hz); 3.71 (s, 2H, CH2); 3.01 (d, 2H, J=12.2 Hz); 2.56-1.50 (m, 2H); 2.23 (m, 5H, CH2&Me); 1.73 (d, 2H, J=12.8 Hz); 1.65-1.50 (m, 1H); 1.07-0.97 (m, 2H). LC-MS (m+1)=455.34
