Reaction Steps
The title compound was prepared according to the procedure in Example 5, step 1 using 2,3-dimethylthiophene (5.00 g, 44.6 mmol), 2.5M BuLi/hexanes (17.9 mL, 44.6 mmol) and benzyl bromide (5.30 mL, 44.6 mmol) in THF (44.6 mL). Purification on Biotage KP-Sil eluting with 1% EtOAc/pet ether gave 6.96 g (77%) of the title compound as an oil. 1H NMR (DMSO-d6) δ2.01 (s, 3H), 2.21 (s, 3H), 3.98 (s, 2H), 6.58 (s, 1H), 7.18-7.37 (m, 5H).
