Reaction Steps

To a solution of (1S,4S)-5-[7-(2-chlorophenyl)-8-(4-chlorophenyl)-2-methylpyrazolo[1,5-a][1,3,5]triazin-4-yl]-2,5-diazabicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (8A-1; 200 mg, 0.36 mmol) in methylene chloride (3 ml) and methanol (3 ml) was added 1M HCl in diethyl ether (1.8 ml, 1.8 mmol). After stirring overnight, the reaction was concentrated, in vacuo, and then triturated from diethyl ether to afford 9A-1 (180 mg, 96%) as a solid: +ESI MS (M+1) 451.3; 1H NMR (400 MHz, CD3OD) δ 7.48-7.36 (m, 4H), 7.32 (d, J=8.7 Hz, 2H), 7.26 (d, J=8.7 Hz, 2H), 4.64 (s, 1H), 3.68 (d, J=10.8 Hz, 1H), 3.55 (dd, J=10.8, 1.6 Hz, 1H), 2.58 (s, 3H), 2.41 br d, J=11.2 Hz, 1H), 2.18 (d, J=11.2 Hz, 1H).
