Procedure

An ice-cooled solution of 1-t-butoxycarbonyl-2-(S)-azetidinemethanol (from Example 7b, 0.623 g, 3.33 mmol) was allowed to react with 2-methyl-3-hydroxypyridine (0.399 g, 3.66 mmol) under the conditions of Example 2a to yield the title compound (0.511 g, 55%). MS (DCI/NH3) m/e: 279 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ: 8.10 (dd, J=4.4, 1.5 Hz, 1H), 7.15-7.06 (m, 2H), 4.54-4.53 (m, 1H), 4.35-4.34 (m, 1M), 4.07 (dd, J=10.3, 2.6 Hz, 1H), 3.96-3.88 (m, 2H), 2.51 (s, 3H), 2.42-2.31 (m, 2H), 1.40 (s, 9H).
