Procedure:
To a solution of ethyl 5-cyano-4-(3-fluoro-4-nitrophenyl)-1H pyrrole-3-carboxylate (31.9 g, 105.2 mmol) in DMF (1.5 L) was slowly added NaH (34.54 g, 136.7 mmol). After the evolution of gas had ceased (aminooxy)(diphenyl)phosphine oxide (34.4 g, 147.3 mmol) was added in one portion. Upon addition of (aminooxy)(diphenyl)phosphine oxide the reaction mixture solidified. The reaction mixture was heated to 80° C. during which time the solids broke up and mixture stirred freely. The reaction was heated for 3 h, then cooled and the DMF was removed under reduced pressure. The remaining slurry was dissolved in EtOAc (500 mL) and filtered to remove a majority of the phosphinic acid. The filter cake was washed with EtOAc and the organics were concentrated in vacuo. The product was purified by crystallization from hot ACN to provide a tan solid (24.0 g, 75.31 mmol) in 71% yield. 1H-NMR (DMSO-d6) δ 8.21 (app t, J=8.4 Hz, 1H), 7.73 (s, 1H), 7.71 (dd, J=12.4, 2.0 Hz, 1H), 7.48 (m, 1H), 6.72 (s, 2H), 4.11 (q, J=7.2 Hz, 2H), 1.14 (t, J=7.2 Hz, 3H).

Procedure:
To a suspension of 2-(2-cyclopropylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carbaldehyde (500 mg, 1.24 mmol) in EtOH (16 mL) was added AgNO3 (265 mg, 1.56 mmol) followed by a solution of NaOH (302 mg, 7.5 mmol) in H2O (5 mL). The resulting black suspension was allowed to stir at r.t. for 30 min then filtered through Celite® and the resulting filtrate concentrated in vacuo. The resulting residue was dissolved in H2O and basified by the addition of aq. NaOH. The aqueous phase was extracted with DCM then acidified to pH 2 with HCl. The aqueous phase was concentrated in vacuo to half volume then cooled on ice. The resulting precipitate was collected by filtration and dried in vacuo affording the title compound (280 mg, 55%). 1H NMR (DMSO, 400 MHz): δ 8.12-8.11 (1 H, m), 7.72-7.68 (1 H, m), 7.44-7.43 (2 H, m), 4.60 (4 H, brd s), 4.04 (3 H, s), 3.90-3.70 (4 H, m), 3.06-3.00 (1 H, m), 1.33-1.31 (4 H, m)

Procedure:
To a mixture of 148.0 g (1.0 mol) of phthalic anhydride and 15 mL of triethylamine in 1.5 L of xylene was slowly added 108.0 g (1.0 mol) of 4-(Aminomethyl)pyridine with mechanical stirring. The resulting solid was collected by filtration. The N-Pyridin-4-ylmethyl-phthalamic acid was then cyclized, by heating 235 g (0.88 mol) to the melt stage for 15 min. The mixture was allowed to cool slightly and 2.5 L of ethanol was added to the warm reaction mixture, and the solution filtered. Upon cooling, the mixture crystallized to give 188.0 g of 2-Pyridin-4-ylmethyl-isoindole-1,3-dione (m.p. 166-167.5° C.). A mixture of 23.8 g (0.1 mol) of 2-Pyridin-4-ylmethyl-isoindole-1,3-dione and 1.3 g of platinum oxide in 400 mL of methanolic HCl was reduced at 50 psi until no starting material could be detected by TLC. The mixture was filtered through celite and concentrated to give 22.0 g of 2-Piperidin-4-ylmethyl-isoindole-1,3-dione hydrochloride as a white solid. A small sample was recrystallized from ethanol to give an analytically pure sample of 16A (m.p. 241-242.5° C.).

Procedure:
To a stirred solution of sodium bicarbonate (4.0 g) in water (50 ml) layered with ethyl acetate (200 ml) was added solid 2-amino-3,4-dihydronaphthalen-1(2H)-one hydrochloride (4.0 g, 2 mmol). After the solid had dissolved chloroacetylchloride (1.6 ml, 2 mmol) was added dropwise over 10 minutes. After stirring for 1 hr, the ethyl acetate layer was separated, washed with brine and dried over Na2SO4. Evaporation afforded 2.7 g (57%) of a dark solid; m.p. 118°-122° C.

Procedure:
(2R,4S)-1-(p-Nitrobenzyloxycarbonyl)-2-carboxymethyl-4-acetylthiopyrrolidine (148 mg) was dissolved in 2 ml of dry methylene chloride, and 0.2 ml of oxalyl chloride and a catalytic amount of dimethylformamide were added thereto, followed by stirring at room temperature for 2 hours. The reaction mixture was distilled to remove the solvent, and dry benzene was added thereto, followed by distillation of benzene. After two times repetition of the above procedure, the residue was dissolved in 2 ml of dry methylene chloride. The solution was added to a mixture of methanol (125 mg), triethylamine (81 mg) and dry methylene chloride (1 ml) under nitrogen stream with ice-cooling and stirred at the same temperature for 2 hours. The reaction mixture was washed successively with water and dilute hydrochloric acid, dried over anhydrous sodium sulfate and distilled to remove the solvent to obtain (2R,4S)-1-(p-nitrobenzyloxycarbonyl)-2-methoxycarbonylmethyl-4-acetylthiopyrrolidine.
