Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Glycolic Acid | HCID 757 | — |
| Reactant | 6-Isopropoxy-N2-methylpyridine-2,3-diamine | HCID 10821269 | — |
| Product | 3h-Imidazo[4,5-b]pyridine-2-methanol,3-methyl-5-(1-methylethoxy)- | HCID 10822868 | 25% |
Reaction Steps
A procedure similar to that described in Preparation 43 was repeated, except that 1.90 g of 3-amino-6-isopropoxy- 2-methylaminopyridine (prepared as described in Preparation 101), and 2.39 g of glycolic acid were used, and that the product was purified by column chromatography through silica gel, using a 10:1 by volume mixture of ethyl acetate and methanol, to give 0.58 g of the title compound, melting at 125°-127° C.
