Reaction Steps

The title compound was prepared using methods analogous to those described in Synthesis 5-1 using 2-amino-5-cyanopyrazine in place of (R)-5-amino-3-(pyrrolidin-3-yloxy)pyrazine-2-carbonitrile and 6-chloroisoquinolin-3-yl trifluoromethanesulfonate in place of 3,8-dichloroisoquinoline. 6-Chloroisoquinolin-3-yl trifluoromethanesulfonate was prepared using methods analogous to those described in Synthesis 11-1 for 8-bromoisoquinolin-3-yl trifluoromethanesulfonate. 1H NMR (DMSO, 400 MHz) δ 11.11 (s, 1H), 9.24 (s, 1H), 8.82 (d, 1H, J=1.3 Hz), 8.74 (d, 1H, J=1.3 Hz), 8.47 (s, 1H), 8.13 (d, 1H, J=8.6 Hz), 8.09 (d, 1H, J=1.8 Hz), 7.55 (dd, 1H, J=8.8, 2.0 Hz). LCMS (2) Rt=3.04 min, m/z (ESI+) 282 & 284 (MH+).
