Reaction Steps

Compound 60 was prepared using a procedure analogous to that described in connection with compound 1D, except that (S)-7-(hydroxymethyl)-4-isopropyl-3-methyl-3,4-dihydropyrido[3,2-b]pyrazin-2(1H)-one was used instead of (S)-3-(hydroxymethyl)-6a,7,8,9-tetrahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6(5H)-one and 4-(4-chlorophenyl)-1,2,3,6-tetrahydropyridine was used instead of 1-(4-chlorophenyl)piperazine. 1H NMR (CHLOROFORM-d) δ (ppm): 8.33 (s, 1H), 7.84 (d, J=1.8 Hz, 1H), 7.21-7.36 (m, 4H), 7.04 (d, J=1.5 Hz, 1H), 6.06 (br. s., 1H), 4.64-4.84 (m, 1H), 4.28 (q, J=6.7 Hz, 1H), 3.52 (s, 2H), 3.05-3.27 (m, 2H), 2.65-2.79 (m, 2H), 2.54 (br. s., 2H), 1.37 (d, J=6.8 Hz, 3H), 1.25-1.33 (m, 6H); [M+H] calc'd for C23H27ClN4O, 411; found, 411.
