Product 1

HCID 204466596-Benzyloxy-5-(5-ethoxycarbonylpentyl)-imidazo[1,5-a]pyridine

Procedure

The condensation of 6-benzyloxy-5-methylimidazo[1,5-a]pyridine with 5-bromo-1,1,1-triethoxypentane essentially by the procedure described in Example 1 yields 6-benzyloxy-5-(5-ethoxycarbonylpentyl)-imidazo[1,5-a]pyridine; NMR (CDCl3) 1.4 (3H), 4.17 (2H), 4.97 (2H).
