Reaction Steps

Following an analogous procedure to that described in Example 5, the reaction of 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzenesulfonamide and (S)-(2,3,3a,4-Tetrahydro-1H,6H-5-oxa-10b-aza-benzo[e]azulen-8-yl)amine gave 2-{5-Chloro-2-[(S)-(2,3,3a,4-tetrahydro-1H,6H-5-oxa-10b-aza-benzo[e]azulen-8-yl)amino]-pyrimidin-4-ylamino}-N-methyl-benzenesulfonamide, upon purification by flash chromatography (Dichloromethane:MeOH 98:2) followed by trituration with Et2O, as solid (32%)2-{5-Chloro-2-[(S)-(2,3,3a,4-tetrahydro-1H,6H-5-oxa-10b-aza-benzo[e]azulen-8-yl)amino]-pyrimidin-4-ylamino}-N-methyl-benzenesulfonamide; 1H NMR (400 MHz, DMSO-d6) δ9.30 (s, 2H), 8.56 (m, 1H), 8.22 (s, 1H), 7.79 (m, 2H), 7.63 (m, 1H), 7.44 (s, 1H), 7.34 (m, 1H), 7.28 (m, 1H), 6.81 (d, J=8.71 Hz, 1H0, 4.53 (d, J=13.04 Hz, 1H), 4.27 (d, J=13.01 Hz, 1H), 3.88 (d, J=9.54 Hz, 1H), 3.31-3.19 (2m along with water peak, 2H), 2.88 (m, 1H), 2.43 (d, J=4.73 Hz, 3H), 2.07 (m, 1H), 1.84 (m, 1H), 1.47 (m, 1H); MS (m/e) 501, 502 (M+H); mp 187-188° C.
