Procedure:
A 25 mL 3-necked flask equipped with a condenser, a thermometer, and a magnetic stirrer was charged with 0.20 g of ethyl 5-(((3,4-dihydro-2-methyl-4-oxo-6-quinazolinyl)methyl)methylamino)-2-thiophene-carboxylate, 6 mL of EtOH, and 6 mL of 1N aqueous NaOH.

Procedure:
A round bottom flask, equipped with a distillation apparatus, is charged with (1S,2R) -norephedrine (18.16 g, 99.1 mmol), diethyl carbonate (27.6 mL, 228 mmol), and potassium carbonate (28.9 g, 209 mmol), and heated at 160° C.

When the head temperature drops to 60° C. (ca 5 hours), the oil bath is removed and the mixture is cooled to room temperature. The mixture is diluted in dichloromethane and washed with water (2X) and dried (magnesium sulfate). Concentration in vacuo affords an off-white solid (17.88 g), which is recrystallized in hexane-ethyl acetate 1:1.5, to afford the title compound as white crystals, 15.2 g; mp 120°-121° C., [α]D =171.4° (2.042% in chloroform).

Procedure:
A mixture of 4-methoxymethoxymethyl-2-phenyl-1,3-oxazole-5-carbaldehyde (3.00 g), 4-benzyloxybenzyltriphenylphosphonium chloride (6.58 g), potassium carbonate (1.84 g) and N,N-dimethylformamide (50 mL) was stirred at room temperature for 15 hrs. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The organic layer was washed successively with dilute hydrochloric acid and saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography to give a colorless oil from a fraction eluted with ethyl acetate-hexane (1:4, v/v). A mixture of the obtained colorless oil, 5% palladium on carbon (5.00 g) and tetrahydrofuran (200 mL) was stirred under a hydrogen atmosphere at room temperature for 3 hrs. After removing palladium on carbon by filtration, the filtrate was concentrated. The obtained crystals were collected by filtration to give 5-[2-(4-hydroxyphenyl)ethyl]-4-methoxymethoxymethyl-2-phenyl-1,3-oxazole (3.24 g, yield 79%). The crystals were recrystallized from ethyl acetate-hexane. melting point: 102-103° C.

Procedure:
To a stirring, argon-purged solution of 4-picolyl chloride-HCl (15 g, 91.4 mmol) and N-methylformamide (53.4 ml, 914 mmol) in 300 ml of THF at room temperature was added portionwise over a 20 minute period a suspension of 80% NaH (5.48 g, 183 mmol). The reaction was quenched 18 h later by the addition of ice, partitioned between methylene chloride and water, washed with water and brine, dried over MgSO4, and evaporated to dryness to afford a dark oil. Flash chromatography on silica gel provided 10.5 g (76%) of the rifled compounds a pale yellow oil. TLC; silica gel (9:1 CHCl/MeOH) Rf=0.54.
