Diisopropylethylamine → 1-(3-Methoxy-4-(trifluoromethyl)phenyl)-3-(3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio)phenyl)urea

Participants

Reaction Steps

The procedure for Example 138B was used to react phenyl 3-methoxy-4-(trifluoromethyl)phenylcarbamate described in Example 190B (144 mg, 0.46 mmol) with 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio)aniline described in Example 231A (110 mg, 0.31 mmol). To this solution was added diisopropylethyl amine (80 μL, 0.46 mmol) and DMAP (4.0 mg, 0.03 mmol). The reaction was concentrated to dryness and purified by silica gel chromatography eluting with ethyl acetate/dichloromethane 0-50% over 75 minutes. The main peak collected and concentrated, then triturated with dichloromethane to give a solid weighing 43 mg. 1H (DMSO-d6) 9.19 (s, 1H), 9.04 (s, 1H), 8.70 (s, 1H), 7.84 (s, 1H), 7.6-7.40 (m, 4H), 7.35 (m, 2H), 7.25 (m, 1H), 7.00 (m, 1H), 4.34 (m, 2H), 4.00 (s, 3H), 3.84 (s, 3H), 3.78 (m, 2H). LCMS (ESI) m/z 575 (M+H)
