Procedure

The title compound of step 1 (1.2 g) was hydrogenated in MeOH (45 mL) in a manner similar to Example 312, step 2. Preparative HPLC gave the title compound (422 mg, 41%). 1H NMR (CDCl3, 400 MHz): δ 7.19-7.13 (m, 3H), 2.95 (s, 3H), 2.60-2.56 (m, 2H), 1.50-1.44 (m, 2H) 0.68-0.65 (m, 1H), 0.43-0.38 (m, 2H), 0.03-0.01 (m, 2H).
