Procedure

A mixture of 7-[(R)-1-(2,6-Dichloro-3-fluorophenyl)ethoxy]-3-(1,2,3,6-tetrahydropyridin-4-yl)-furo[3,2-c]pyridin-6-ylamine (10.0 mg, 0.0237 mmol), tert-butyl isocyanate (0.0042 g, 0.043 mmol), DIPEA (33 μL, 0.19 mmol) in DMF (1 mL) was stirred at rt for 15 min. Purification by HPLC afforded the title compound as a colorless solid. 1H NMR (400 MHz, CD3OD): δ=1.36 (s, 9H), 1.89 (d, J=6.8 Hz, 3H), 2.49 (br. s., 2H), 3.59 (t, J=5.7 Hz, 2H), 4.04 (d, J=2.5 Hz, 2H), 6.25 (br. s., 1H), 6.48-6.53 (m, 1H), 7.22 (t, J=8.7 Hz, 1H), 7.40 (dd, J=9.0, 4.9 Hz, 1H), 7.65 (s, 1H), 8.20 (s, 1H). MS (ES+): m/z 521.07/523.09 (100/72) [MH+]. HPLC: tR=3.37 min (ZQ3, polar—5 min).
