Triethylamine → phenyl 1-(2-pyrrolidin-1-ylethyl)-1H-indazol-6-ylcarbamate

Participants

Reaction Steps

To a mixture of 1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-6-ylamine (0.220 g, 0.955 mmol) and triethylamine (0.240 mL, 1.72 mmol) in 1 mL of THF at 0 C was slowly added phenyl chloroformate (0.246 ml, 1.72 mmol). The mixture was stirred cold for 1 hours and the formed precipitate collected by filtration with rinsing with ether to provide the title compound. 1H NMR (300 MHz, DMSO-D6) δ ppm 1.82 (m, 2 H), 1.97 (m, 2 H), 2.97 (m, 2 H), 3.49 (m, 2 H), 3.69 (m, 2 H), 4.71 (t, J=6.27 Hz, 2 H), 7.19 (m, 1 H), 7.28 (m, 3 H), 7.46 (m, 2 H), 7.74 (m, 1 H), 7.99 (m, 1 H), 8.10 (s, 1 H), 10.51 (s, 1 H); MS (DCI/NH3) m/z 351 [M+H]+.
