Reaction Steps

A vial equipped with a flea stirbar was charged with (±)-(E)-1-(3-amino-7-bromo-2,3-dihydrospiro[indene-1,4′-piperidine]-1′-yl)-3-(2-(trifluoromethyl)phenyl)prop-2-en-1-one TFA salt (9 mg, 0.015 mmol), i-Pr2NEt (0.01 mL) and CH2Cl2 (1 mL). MeNCO (0.05 mL, 0.085 mmol) was added. The mixture was stirred at rt for 3 h and evaporated to dryness. The residue was purified by prep HPLC to afford (±)-(E)-1-(7-bromo-1′-(3-(2-(trifluoromethyl)phenyl)acryloyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)-3-methylurea (2.9 mg, 59%). LC-MS Method 1 tR=1.77, min, m/z=536, 538.
