Procedure

The procedure in 138B was used to react the carbamate from Example 157A (123 mg, 0.45 mmol) with 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy)aniline from Example 117B (103 mg, 0.30 mmol). To this solution was added diisopropylethyl amine (78 μL, 0.45 mmol) and DMAP (3.6 mg, 0.03 mmol). The reaction was concentrated to dryness. The resulting oil purified by silica gel chromatography eluting with ethyl acetate/dichloromethane 10-50% over 60 minutes. The main peak concentrated to a solid weighing 126 mg. 1H (DMSO-d6) 9.10 (s, 1H), 8.70 (s, 2H), 7.65 (m, 2H), 7.50 (m, 2H), 7.30 (m, 1H), 7.15 (s, 1H), 6.95 (m, 1H), 6.00 (s, 1H), 4.40 (s, 2H), 4.00 (s, 3H), 3.85 (s, 2H), 3.60 (s, 3H), 3.40 (s, 3H), 1.25 (s, 9H).
