실험 절차

The title compound (0.003 g) was prepared from 3-(4-chloro-phenyl)-4,5,7,8-tetrahydro-1H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 59, Step C, 0.1 g) using methyl 4-chlorobutyrate (0.8 mL) in place of benzyl chloride. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-(3-methoxycarbonyl-propyl)-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester in the alkylation step. MS (ESI): exact mass calculated for C18H22ClN3O2, 347.14. found, m/z 348.1 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.37-7.31 (m, 4H), 4.07 (t, J=6.6 Hz, 2H), 3.52 (s, 3H), 2.97-2.94 (m, 2H), 2.88-2.84 (m, 4H), 2.70-2.66 (m, 2H), 2.25 (t, J=6.6 Hz, 2H), 1.98-1.95 (m, 2H).
