Reaction Steps

N-methyl-5-(4-morpholino-6-((4-N-methylsulfonylpiperazin-1-yl)methyl)thieno[3,2-d]pyrimidin-2-yl)pyridin-2-amine 195 (1 eq.) was stirred with acetyl chloride (1 eq.) and NEt3 (1 eq.) in dry CH2Cl2 (10 mL) at R.T. overnight. Water/CH2Cl2 work up then purification on silica yielded 196 (28%). NMR (CDCl3): 2.17 (s, 3H, CH3), 2.69-2.70 (m, 4H, 2×CH2), 2.81 (s, 3H, CH3), 3.31 (m, 4H, 2×CH2), 3.44 (s, 3H, CH3), 3.88-3.90 (m, 6H, 3×CH2), 4.04-4.07 (m, 4H, 2×CH2), 7.33 (s, H, ArH), 7.39 (m, H, ArH), 8.70 (dd, H, ArH, J=6.08 Hz, 2.3 Hz), 9.47 (d, H, ArH, J=2.12 Hz). MS: (ESI+): MH+ 546.34
