3-methylpyrrolidine;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In analogy to the procedure described for the synthesis of 5-tert-butyl-3-(2-chlorobenzyl)-7-morpholin-4-yl-3H-[1,2,3]triazolo[4,5-d]pyrimidine (example 1, step c), the title compound was prepared from 5-tert-butyl-7-chloro-3-(2-chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 3-methylpyrrolidine hydrochloride. MS (m/e): 385.3 (MH+).

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2,5-Dibromothiazole (250 mg, 1.029 mmole), 3-methyl-pyrrolidine hydrochloride (188 mg, 1.544 mmole), and K2CO3 (569 mg, 4.12 mmole) were combined in DMF (5 mL) then heated to 100° C. After stirring overnight the mixture was cooled to RT, diluted with H2O and extracted with EtOAc (3×). The combined organic layers were washed with H2O and brine, dried (MgSO4), filtered, and concentrated. Flash column chromatography (Biotage-SNAP-10 g SiO2, 0-50% EtOAc/hexanes) gave the title compound (234 mg, 92%) as a pale yellow oil. 1H NMR (399 MHz, CDCl3): δ 7.06 (s, 1 H); 3.58-3.45 (m, 2 H); 3.45-3.35 (m, 1 II); 2.97 (dd, J=9.7, 7.7 Hz, 1 H); 2.47-2.36 (m, 1 H); 2.20-2.10 (m, 1 H); 1.73-1.63 (m, 1 H); 1.12 (d, J=6.7 Hz, 3H). was cooled to RT extracted with EtOAc (3×) The combined organic layers were washed with H2O and brine dried (MgSO4) filtered concentrated
