Procedure
This material was prepared from 6-methoxy-1-methyl-indole-3-carboxylic acid 16b (515 mg, 2.5 mmole), oxalyl chloride (0.9 ml, 12.6 mmole) and methylamine (7.5 mmole) in a manner as previously described for example 16d to give 457 mg of a pale brown solid (83%). 1H NMR (CD3OD) δ7.83 (1H, d, J=8.7 Hz), 7.51 (1H, s), 6.81 (1H, d, J=2.3 Hz), 6.72 (1H, dd, J=2.3, 8.7 Hz), 3.75 (3H, s), 3.67 (3H, s), 2.80 (3H, s); ESIMS (MH+): 219.05.
