Reaction Steps
The title compound was prepared according to the procedure in Example 5, step 2 using 3,5-diisopropyl-p-anisic acid (1.03 g, 4.35 mmol, RN-117439-59-5), oxalyl chloride (0.417 mL, 4.79 mmol), N,N-dimethylformamide (2 drops), tin (IV) chloride (0.560 mL, 4.79 mmol) and 2-(4-bromo-benzyl)-4,5-dimethyl-furan (1.15 g, 4.35 mmol) in CH2Cl2. Purification on Biotage KP-Sil eluting with 3% EtOAc/pet. ether gave 1.63 g (77%) of the title compound as a yellow clear oil. 1H NMR (DMSO-d6) δ1.16 (d, 12H), 1.80 (s, 3H), 2.19 (s, 3H), 3.28 (septet, 2H), 3.74 (s, 3H), 3.83 (s, 2H), 6.98 (d, 2H), 7.41 (dd, 2H), 7.44 (s, 2H).
