2-(chloromethyl)-1,3-diethylbenzene

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

Procedure: To a mixture of (2,6-diethylphenyl)methanol (1.83 g, 11.1 mmol), toluene (20 mL) and DMF (6 drops) was added SOCl2 (2.1 g, 1.6 eq). The resulting solution was stirred at RT (1 h). After evaporating to dryness, the residue was taken up in heptane (−50 mL) and washed with water (−5 mL), dried (Na2SO4), filtered and evaporated to give 1.97 g (yield of 97%) of title product. 1H NMR (300 MHz, CDCl3) δ 1.28 (t, 6H), 2.79 (q, 2H), 4.70 (s, 2H), 7.09 (d, 2H), 7.20 (m, 1H). After evaporating to dryness washed with water (−5 mL) dried (Na2SO4) filtered evaporated

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

Procedure: 8-Amino-2,3-dimethylimidazo[1,2-a]pyridine-6-carboxamide mesylate (4.0 g, 10.7 mmol), 2,6-diethylbenzylchloride (1.8 g, 9.9 mmol), diisopropylethylamin (3.0 g, 23.3 mmol) were stirred in dimethylformamide (20 ml) at 50° C. overnight and at 70° C. for 3 h. Water (60 ml) and methylene chloride were added and the organic layer was separated, dried and evaporated under reduced pressure. The residue was treated with diethyl ether and the product was filtred off to give 1.7 g (45%) of the title compound. the organic layer was separated dried evaporated under reduced pressure The residue was treated with diethyl ether

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