Reaction Steps

(±)-(E)-2-(trimethylsilyl)ethyl 7-bromo-1′-(3-(2-(trifluoromethyl)phenyl)acryloyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-ylcarbamate (16.5 mg, 0.026 mmol) and Et4NF (30 mg) were dissolved in MeCN (3 mL). The solution was heated at 100° C. for 10 min in a microwave. The solution was concentrated and the residue was purified by preparative HPLC to give (±)-(E)-1-(3-amino-7-bromo-2,3-dihydrospiro[indene-1,4′-piperidine]-1′-yl)-3-(2-(trifluoromethyl)phenyl)prop-2-en-1-one (11 mg, 70%) as its TFA salt. LC-MS Method 1 tR=1.38, min, m/z=479, 481; 1H NMR (CD3OD) 1.53 (m, 1H), 1.67 (m, 1H), 2.08 (m, 1H), 2.55 (m, 1H), 2.9-3.5 (5H), 4.38 (d, 1H), 4.72 (d, 1H), 7.2-8.0 (9H).
