To a solution of 4-benzyloxy-3-methoxyphenylacetyl chloride (18 mmol), the product of Example 4, in 50 mL of methylene chloride was added 50 mL of saturated aqueous sodium bicarbonate solution, followed by a solution of 1-aminomethyl-1-hydroxyindan (3.15 g, 19 mmol), the product of Example 1, in 20 mL of methylene chloride. The resulting two-phase mixture was stirred vigorously at ambient temperature for 2 hours. The aqueous and organic phases were separated and the aqueous phase was extracted with methylene chloride (75 mL). The combined organic layers were washed with 100 mL of 1M aqueous hydrochloric acid solution, dried over anhydrous magnesium sulfate, filtered and concentrated to give a yellow oil. The oil was purified by flash chromatography on silica gel eluting with 1:1 ethyl acetate/methylene chloride to give 6.17 g (82% yield) of the title compound as a white solid; 1H NMR (CDCl3).δ.1.96-2.08 (m, 1H), 2.18-2.28 (m, 1 H), 2.67-2.80 (m, 1H), 2.87-2.98 (m, 1H), 3.29-3.37 (m, 2H), 3.53-3.65 (m, 3H), 3.88 (s, 3H), 5.16 (s, 2H), 5.80-5.88 (m, 1H), 6.71 (dd, 1H, J=8.7, 3.0 Hz), 6.79 (d, 1H, J=3.0 Hz), 6.85 (d, 1H, J=8.7 Hz), 7.10-7.47 (m, 9H).
