Procedure

Using a similar protocol as described in Example 9A but employing 1C (500 mg, 1.55 mmol) and 3-chloro-4-hydroxybenzaldehyde (250 mg, 1.60 mmol) as starting materials gave 205 mg (34%) of 10A as a solid. 1H NMR (500 MHz, CD3OD): δ 4.33 (m, 1H), 4.6-4.9 (m, 2H), 5.23 (m, 1H), 5.36 (m, 1H), 7.07 (d, 1H), 7.5-7.7 (m, 3H), 7.8-9.0 (m, 4H), 9.86 (s, 1H).
