Versuchsvorschrift

Fluoro-2-methyl-4-triethylsilyl-but-3-yn-2-ol (80 mg) was stirred for 24 hrs at room temperature with potassium carbonate (3 eq) in Methanol (1 mL) after which the carbonate was filtered and the resulting methanol was dried down to a viscous oil. This intermediate 1-fluoro-2-methyl-but-3-yn-2-ol was reacted (in accordance with a procedure described in Procedure E) with 10-bromo-3-(morpholinomethyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide (30 mg) to afford 1.9 mg of (±) 10-(4-fluoro-3-hydroxy-3-methyl-but-1-ynyl)-3-(morpholinomethyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide [MS (Q1) 429 (M)+] and 6.4 mg of (±) 10-(3-hydroxy-4-methoxy-3-methyl-but-1-ynyl)-3-(morpholinomethyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide [MS (Q1) 441 (M)+]. 1H NMR (400 MHz, DMSO) δ 8.49 (d, J=2.1 Hz, 1H), 7.56 (s, 1H), 7.29 (dd, J=8.5, 2.2 Hz, 1H), 7.10 (s, 1H), 7.02 (d, J=8.5 Hz, 1H), 5.53 (s, 1H), 4.54-4.42 (m, 5H), 3.98 (s, 2H), 3.57-3.48 (m, 6H), 3.37 (s, 4H), 2.41-2.37 (m, 4H), 1.43 (s, 4H)] following reverse phase purification.
