Procedure
This compound (c-1) was prepared in an analogous fashion to (S)-4-(2-chloro-9-methyl-6-(3-methylmorpholino)-9H-purin-8-yl)tetrahydro-2H-pyran-4-ol, using tert-butyl 3-oxoazetidine-1-carboxylate as the starting material. 1H NMR (CDCl3, 400 MHz) δ ppm 5.17 (broad d, 2H), 4.56 (dd, J=16.9, 9.48 Hz, 2H), 4.21 (dd, J=9.48. 2.56 Hz, 1H), 4.04 to 3.96 (m, 1H), 3.82 to 3.71 (m, 5H), 3.59 (td, J=11.6, 2.6 Hz, 1H), 3.47 (broad s, 1H), 2.02 (s, 1H), 1.43 (s, 9H), 1.40 to 1.36 (m, 4H); LC-MS (method A)=439/441 [M+H]+, RT=2.56 min.
