Reaction Steps

This compound was prepared using Step 2 intermediate from Intermediate 2 (1.00 g, 2.160 mmol), (2-isobutoxy-3-methoxy)benzaldehyde (494 mg, 2.376 mmol) and NaH (95 mg, 3.958 mmol) in dry DMSO (10 ml) according to the procedure outlined in Intermediate 2, Step 3 to yield a crude residue which was purified by column chromatography using 2% ethyl acetate in DCM to afford the 500 mg of the desired compound as a white solid: 1H NMR (300 MHz, DMSO-d6) 1.05 (d, J=6.9 Hz, 6H), 2.01-2.06 (m, 1H), 3.69 (d, J=6.3 Hz, 2H), 3.80 (s, 3H), 6.28 (s, 1H), 6.94-7.18 (m, 3H), 7.34 (d, J=6.3 Hz, 1H), 7.47 (d, J=5.1 Hz, 1H), 7.97 (d, J=4.8 Hz, 1H), 8.09 (d, J=16.2 Hz, 1H).
