Reaction Steps

To a solution of 1-tert-butylazetidin-3-ol (19 mg, 0.15 mmol), 1,4-diazabicyclo[2.2.2]octane (11 mg, 0.10 mmol), and diisopropylethylamine (0.026 ml, 0.15 mmol) in tetrahydrofuran (1 ml) was added 4-chloro-7-(2-chlorophenyl)-8-(4-chlorophenyl)-2-methylpyrazolo[1,5-a][1,3,5]triazine (I-2A-1b; 39 mg, 0.10 mmol), portionwise. After stirring for 2 days, the reaction was concentrated, in vacuo, and the residue purified on a Biotage™ Flash 12S column using 20-40% ethyl acetate in hexanes to afford 11A-1 (25 mg, 52%) as a solid: +APcI MS (M+1) 482.3; 1H NMR (400 MHz, CD3OD) δ 7.52-7.42 (m, 4H), 7.39 (d, J=8.3 Hz, 2H), 7.24 (d, J=8.3 Hz, 2H), 5.58 (quintet, J=6.2 Hz, 1H), 3.80-3.75 (m, 2H), 3.63-3.58 (m, 2H), 2.60 (s, 3H), 1.04 (s, 9H).
