Reaction Steps

A mixture of 26.7 g of the tosylate of 7-methoxy-3-benzofuranethanol (Example 2a), prepared as described in Example 1b, 300 ml of tetrahydrofuran and 100 g of ammonia was heated in a pressure vessel to 100° for 4 hours. The crude product was partitioned into basic and neutral fractions, and the basic fraction short-path distilled (to 170° bath temperature, 1 micron pressure) to give 11.2 g (76%) of 7-methoxy-3-benzofuranethylamine; nmr spectrum (in CDCl3): τ2.6 (s, 1); 2.9-3.4 (m, 3); 6.1 (s, 3); 6.9-7.5 (m, 4) and 8.9 (s, 2).
