Procedure
Isobutyl chloroformate (27 μl, 0.21 mmol) was added to a cooled (5° C.) suspension of Example 64 (90 mg, 0.19 mmol) and N-methyl morpholine (23 μl, 0.2 mmol) in DCM (4 ml). After 1 h, ammonia (420 μl, 0.5 M in dioxane, 0.21 mmol) was added. After 1 h at 5° C. and 3 h at RT, water (2 ml) was added. The organic layer was separated and the aqueous layer extracted with DCM. The combined organic layers were concentrated in vacuo and the resulting material was purified by chromatography over silica gel (eluent: DCM/MeOH 95/5) to yield the above-titled compound as a solid (49.6 mg). 1H NMR (CDCl3): 7.64 (2H, d, J=8.2 Hz), 7.25-7.30 (3H, m), 6.84 (1H, br s), 6.65 (2H, d, J=1.5 Hz), 6.18 (1H, br s), 3.87 (1H, t), 3.4-3.5 (5H, m), 3.24 (3H, s), 3.15 (1 H, d, J=10.9 Hz).
