Participants

Reaction Steps

Using the method of Example 305, using 2-trifluoromethyl-4,9-dihydro-3-thia-1,4,9-triaza-benzo[f]azulene-10-thione and methyl trifluoromethanesulfonate, and 2-(S)-(2-methoxy-ethyl)-piperazine, followed by purification, eluting with a gradient of a 7% solution of 2M ammonia in methanol, in dichloromethane (0-100%), gives the title compound: mass spectrum (APCI, m/e): 412 (M+1); NMR (1H, 300 MHz, DMSO-d6): δ 8.71 (br. s, 1H), 8.60 (s, 1H), 6.93 (m, 3H), 6.71 (m, 1H), 4.07 (br. m, 2H), 3.46-3.29 (m, 4H), 3.29-3.06 (m, 5H), 2.99 (m, 1H), 2.48 (m, 2H).
