Procedure

A mixture of 6-(4-fluorophenoxy)-8-methyl-2-(methylsulfonyl) pyrido[2,3-d]pyrimidin-7(8H)-one (see Example 8 made by replacing methyl 2-fluorophenoxyacetate with methyl 4-fluorophenoxyacetate—Steps A and B, 0.35 g, 1.0 mmol) and benzylamine (0.33 mL, 3 mmol) in 0.5 mL of 1-methyl-2-pyrrolidinone was stirred at 110° C. for 12 hours and then cooled to room temperature. Methanol (2 mL) was added and the suspension was stirred for 30 minutes. Filtration and washing of the precipitate thoroughly with methanol followed by drying provided the free amine. This was dissolved in ethyl acetate (1-2 mL) and hydrochloric acid in ether (1M, 1.5 eq) was added. Isolation of the solid via filtration and drying provided 0.317 g of the hydrochloride salt (Mass spec. M+1=377, MP=203.2-204° C.).
