Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-methoxymethyl-4-piperazin-1-yl-pyrimidine (prepared according to the method of Preparation One, 2.08 g, 10 mmol) and triethylamine (1.01 g, 10 mmol) in tetrahydrofuran (20 mL) was added N-pyrrolidinesulfonyl chloride (1.69 g, 10 mmol) at 0° C. and stirred for 3 h at ambient temperature. The mixture was diluted with ethyl acetate and washed twice with water. The organic layer was separated, dried over magnesium sulfate, filtered, and the filtrate was concentrated to an oil which was purified by flash chromatography (95:5 dichloromethane:methanol) to give the title compound of Example 121, Step A as a clear oil, 3.24 g (93%). 1H NMR (CDCl3, 300 MHz) δ 1.81-1.85 (m, 4H), 3.12-3.18 (m, 8H), 3.59 (s, 3H), 3.81(m, 4H), 4.43 (s, 2H), 6.71 (d, 1H), 8.18 (d, 1H); MS (TS) 342 (MH+). washed twice with water The organic layer was separated dried over magnesium sulfate filtered the filtrate was concentrated to an oil which was purified by flash chromatography (95:5 dichloromethane:methanol)

Procedure: Pyrrolidine-1-sulfonyl chloride (CAS 1689-02-7) (56 mg, 0.92 mmol) was added to a solution of tert-butyl 6-(3-amino-5-fluorophenyl)pyrido[3,2-d]pyrimidin-4-ylcarbamate (33-A) (300 mg, 0.84 mmol) in pyridine at ice bath. After the reaction mixture was stirred at 60° C. for 4 h, it was partitioned between water and EtOAc and purified by prep-TLC (PE:EtOAc=2:1) to give title product (250 mg, 61%). it was partitioned between water and EtOAc purified by prep-TLC (PE:EtOAc=2:1)
