On October 12, 2006, Connolly, Stephen; Skrinjar, Marco published a patent.Reference of 3-(2-Methoxyphenoxy)benzaldehyde The title of the patent was Preparation of novel diazaspiroalkanes and their use for treatment of CCR8 mediated diseases. And the patent contained the following:
The title compounds I [R = pyridine N-oxide; R1 = II, III; R3 = OMe, OEt; R4 = H, OMe, OEt], useful in treating CCR8 mediated diseases such as asthma, COPD and rhinitis, were prepared E.g., a multi-step synthesis of IV, starting from tert-Bu 3,9-diazaspiro[5.5]undecane-3-carboxylate hydrochloride and 3-phenoxybenzaldehyde, was given. IV showed IC50 of 2.67 μM against human recombinant chemokine CCR8 receptor binding. Pharmaceutical compositions containing compounds I and their use in therapy are disclosed. The experimental process involved the reaction of 3-(2-Methoxyphenoxy)benzaldehyde(cas: 66855-92-3).Reference of 3-(2-Methoxyphenoxy)benzaldehyde
