Procedure

A solution of 2,4-difluoro-benzoylchloride D in a solution of methylamine and tetrahydrofuran (THF) is allowed to react to produce 2,4-difluoro-N-methylbenzamide M (quantitative yield). The 2,4-difluoro-N-methylbenzamide M is mixed with in a solution of acetonitrile and 4-methoxy-benzenemethanamine and heated in a microwave for 20 minutes at 190° C. to produce 2-fluoro-4-(4-methoxybenzylamino)-N-methylbenzamide S (yield of 40%). The 2-fluoro-4-(4-methoxybenzylamino)-N-methylbenzamide S is reacted in a solution of dichloromethane and trifluoroacetic acid to produce 2-fluoro-4-amino-N-methylbenzamide T (yield greater than 95%). The 2-fluoro-4-amino-N-methylbenzamide T is reacted with a solution of sodium cyanide and cyclobutanone to produce 4-(1-cyanocyclobutylamino)-2-fluoro-N-methylbenzamide B.
