Tert-butyl 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoate → 5-Cyclopropyl-4-((7,7-difluorobicyclo[4.1.0]heptan-1-yl)methoxy)-2-fluorobenzoic acid

Participants

Reaction Steps

Following the procedure as described in Example 332 Step 6 and making non-critical variations to replace tert-butyl 4-((2-cyanoadamantan-2-yl)methoxy)-5-cyclopropyl-2-fluorobenzoate with tert-butyl 5-cyclopropyl-4-((7,7-difluorobicyclo[4.1.0]-heptan-1-yl)methoxy)-2-fluorobenzoate, the title compound was obtained (0.48 g, 80%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 7.53 (d, J=8.4 Hz, 1H), 6.51 (d, J=12.6 Hz, 1H), 4.00-3.90 (m, 2H), 1.97-1.71 (m, 5H), 1.47-1.22 (m, 5H), 0.95-0.86 (m, 2H), 0.69-0.61 (m, 2H).
