Procedure
Compound 430C (1.81 g, 85%) was prepared from 4-chloro-3-cyano-5-methyl-pyrrolo[1,2-b]pyridazine-6-carboxylic acid methyl ester (prepared using the procedure of Example 1D) (1.25 g, 5.0 mmol) and 430B (1.08 g, 5.0 mmol) by a route analogous to that used for the preparation of compound 388D. It is a white solid, and has a retention time of 6.74 min (∠Cl, 8 min run). MS found, (M+H)+=429.2
