Procedure
From 108b (7.0 g, 23.4 mmol) and NaBH4 (4.4 g, 117 mmol), a similar procedure as described for 109a gave 109b (5.4 g, 76.6%) as white crystals: mp 64°-6° C. after recrystallization from ethanol. 1H NMR (200 MHz, CDCl3) δ7.03 (d, J=8 Hz, 2H), 6.61 (s, 2H), 6.62 (d, J=8 Hz, 2H), 4.24 (s, 2H), 3.84 (s, 9H) 2.55 (q, J=8 Hz, 2H), 1.19 (t, J=Hz, 3H). EIMS m/e 301 (M+, 34).
