This compound was prepared using a similar procedure to that described in Stage 3 of Example 1 except that 5-amino-5-methylhex-3-yne hydrochloride was used in place of 4-amino-4-methylpent-2-yne hydrochloride and 2-(5-bromo-3-pyridyloxy)butyric acid was used in place of 2-(5-chloro-3-pyridyloxy)butyric acid. The compound was characterised as follows: colourless solid, m.p. 90–92° C.; 1H NMR (CDCl3) δ: 1.02–1.06 (3H, t); 1.10–1.14 (3H, t); 1.62 (6H, s); 1.96–2.02 (2H, m); 2.16–2.22 (2H, m); 4.424.46 (1H, m); 6.30 (1H, br s); 7.40 (1H, m); 8.30 (1H, d); 8.36 (1H, d).
