Versuchsvorschrift

6-(4-Methoxybenzyl)-9-(piperazin-1-ylmethyl)pyrido[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-5(6H)-one (Example 65, 34 mg, 0.09 mmol), ACN (1 mL), TEA (75 μl, 0.53 mmol), and methane sulfonyl chloride (50 mg, 0.44 mmol) were combined and the mixture was stirred for 4 h. The reaction was filtered through a plug of C18. Purification (HPLC, 10-70% ACN in water) afforded the title compound (17 mg, 33%) as a white solid. 1H NMR (400 MHz, CDCl3 and DMSO-d6) δ 2.48 (d, J=1.63 Hz, 2H), 2.76 (d, J=2.26 Hz, 3H), 3.09 (br s, 4H), 3.54 (br s, 4H), 3.65 (d, J=2.51 Hz, 3H), 4.21 (br s, 2H), 5.63 (d, J=1.76 Hz, 2H), 6.72 (dd, J=8.78, 2.26 Hz, 2H), 7.47 (dd, J=8.66, 2.38 Hz, 2H), 8.26 (d, J=2.38 Hz, 1H), 8.85 (br s, 1H), 9.00 (br s, 1H). [M+H]=484.2.
